In most cases, the error appears right after a successful SSO authentication. This indicates that the user’s credentials are valid, but they do not have the required permissions. The problem is tied to the “Assignment required” setting, which enforces the principle of least privilege and blocks anyone without explicit access.

While error code 50105 is primarily linked to a missing assignment, other factors can also trigger it. Common examples include:

• Provisioning gaps – incomplete automation or overlooked onboarding steps.
• Policy conflicts – Conditional Access rules or misconfigured enterprise apps.
• Token issues – malformed or expired tokens preventing valid authorization.
• Account restrictions – temporary lockouts after repeated sign-in attempts.
• Network-related blocks – access denied from IP addresses flagged for suspicious activity.

The most direct way to resolve this error is to grant the guest user explicit access to the Enterprise Application in Microsoft Entra ID. Doing so ensures they are provided with the required permissions or role. Since the “Assignment required” setting enforces strict access control, users without an explicit assignment are automatically blocked. By adding the assignment, the authorization requirements are met, allowing the guest user to sign in without further restrictions.

1. Open your web browser.
2. Navigate to the Microsoft Entra admin center.
3. Sign in as a Cloud Application Administrator or Global Administrator.
4. Go to Identity>Applications>Enterprise applications.
5. Search for and select the target application.
6. In the application pane, under the Manage section, click Users and groups.
7. Click the “+ Add user/group” button.
8. On the Add Assignment pane, select None Selected under Users and groups.
9. Search for and choose the guest user who requires access (for example, user@abc.com).
10. Under Select a role, choose the appropriate app role (for example, Standard user). If the app has no roles, this step can be skipped.
11. Click Assign to grant access.

To minimize the risk of this error recurring, organizations should apply several preventive measures:

• Immediately assign guest users to the right groups when they are invited.
• Use security groups and group-based licensing to simplify dynamic access control.
• Run Microsoft Entra ID Access Reviews regularly to remove outdated or unnecessary permissions.
• Enforce MFA for all guest accounts, and configure cross-tenant MFA trust if needed.
• Reduce browser-related issues by clearing the cache or using an incognito session when signing in.

Even with WebView2 installed, the setup also depends on certain Windows services to function properly. Services like Windows Installer, Background Intelligent Transfer Service (BITS), and Windows Update are directly responsible for downloading, extracting, and verifying installation files. If any of these are disabled or not running, the installer may stall, loop, or fail.

Another common issue is leftover files from previous installations. Corrupted data or registry entries can block updated components or lock system paths required by the installer. Deleting these remnants ensures the setup runs in a clean state.

Now that the causes are clear, let’s move on to the proven fixes that will help get Razer Cortex running again.

1. Install Microsoft Edge WebView2 Runtime

A missing or corrupted WebView2 Runtime is one of the main reasons why the installer fails to load. Installing it manually ensures Razer Cortex has the required component to start correctly.

1. Open your browser and visit the official Microsoft Edge WebView2 Runtime download page.
2. Scroll down and download the Evergreen Standalone Installer.
3. Run the installer and follow the on-screen instructions to complete setup.
4. When finished, restart your PC and try launching the Razer Cortex installer again.

2. Perform a Clean Boot

A clean boot helps identify if third-party applications or background services are interfering with the Razer Cortex installer. Running Windows with only essential services reduces conflicts and isolates the problem.

1. Press Windows + R, type msconfig, and click OK.
2. Go to the Services tab and check Hide all Microsoft services.
3. Click Disable all to turn off every non-Microsoft service.
4. Switch to the Startup tab and select Open Task Manager.
5. In Task Manager, right-click each startup item and choose Disable.
6. Close Task Manager, return to System Configuration, and click OK.
7. Restart your computer and run the installer again.

3. Ensure Required Services Are Running

The Razer Cortex installer depends on several Windows services. If any are disabled, the installer may freeze, fail to extract files, or stop responding.

1. Press Windows + R, type services.msc, and press Enter.
2. In the Services window, check the following:

   Windows Installer
   Background Intelligent Transfer Service (BITS)
   Windows Update

3. Right-click each service, choose Properties, and set Startup type to Manual or Automatic.
4. If a service is stopped, click Start.
5. Click Apply and OK to save changes.
6. Restart your PC and try the installer again.

4. Disable Third-Party Antivirus Software Temporarily

Some third-party antivirus programs may incorrectly block the Razer Cortex installer, stopping it from writing files or accessing system directories. Temporarily disabling the antivirus helps rule out this conflict.

1. Right-click the antivirus icon in the system tray (bottom-right corner).
2. Select an option such as Disable protection, Turn off antivirus, or Pause protection.
3. Restart your computer and try the installer again.

5. Delete Razer Cortex Files and Folders

Corrupted or leftover files from previous installations can interfere with the new setup. Removing them ensures the installer runs in a completely clean state.

1. Press Windows + R, type appwiz.cpl, and press Enter.
2. Locate Razer Cortex, right-click it, and select Uninstall.
3. After uninstalling, press Windows + E to open File Explorer.
4. Delete all remaining Razer folders from these locations:

   C:\Program Files (x86)\Razer
   C:\ProgramData\Razer
   C:\Users\<YourUserName>\AppData\Local\Razer
   C:\Users\<YourUserName>\AppData\Roaming\Razer

   

5. Empty the Recycle Bin and restart your PC.
6. Run the Razer Cortex installer again.

If the issue persists, consider upgrading to Windows 11 if you are still on Windows 10. For users already on Windows 11, the best option is to contact Razer Support. Their team can provide tailored assistance to fully resolve the problem.

Prerequisites: Update your GPU drivers first and confirm your device supports DirectX 11 or OpenGL 2.0. Driver updates frequently resolve black screen, freeze, and instant crash at launch.

This can be caused by:

• Graphics driver or API issues: Outdated or faulty GPU drivers block OpenGL initialization, which leads to black screen, instant crash, or a stuck splash phase.
• Corrupted app data: Damaged preferences or cache in the user profile stops the app from completing early checks that occur before the window is shown.
• Broken launch path: A desktop shortcut that points to an invalid location prevents Windows from loading the correct executable.
• VPN or proxy interference: Network filtering can delay or block early service calls during startup, which can stall or abort the session.
• Window placement errors: After a display layout change, the window can open off screen with valid process activity but no visible UI.

Now that you know the issue and its likely causes, follow the steps below to fix it. 

1. Open Google Earth Using Search Bar

Launching Google Earth from the Windows search bar avoids broken desktop shortcuts and ensures Windows runs the executable from the correct installation folder. It bypasses a corrupt or stale shortcut target and calls the executable from the installation folder. If this resolves the issue, create a fresh desktop shortcut from the running app.

1. Press Win + S, type Google Earth, then select Open.

2. Disable VPN or Proxy

VPN or proxy services can interrupt a stable connection to Google Earth servers, which prevents the app from launching correctly or loading maps. Disabling the VPN on your computer allows the app to connect normally.

1. Open your VPN client.
2. If the VPN is enabled, click Disconnect to turn it off.
3. Restart the computer, then relaunch Google Earth.

Note for managed networks: If your organization requires a proxy, verify credentials and allow-list Google Earth domains such as kh.google.com and related service endpoints instead of turning the proxy off.

3. Repair Corrupted Files Using Repair_tool.exe

Repair_tool.exe installs with Google Earth and checks for issues such as corrupted installation files and missing or broken registry entries. Running the tool restores default settings and repairs files that block the app from launching.

Before you begin: Close Google Earth completely. The repair tool runs while the app is closed. Default path: C:\Program Files\Google\Google Earth Pro\client\repair_tool.exe.

1. Right click Google Earth > Open file location.
2. Locate Repair_tool.exe.
3. Run Repair_tool.exe as administrator.
4. Click Restore default settings.
5. Click Reset to confirm.
6. Restart the computer, then relaunch Google Earth.

4. Restore Hidden Google Earth Window

In some cases, Google Earth launches but does not appear on the screen. This can happen when the window opens off screen after you change your monitor setup, for example moving from a dual monitor to a single monitor. The program may be running, but you do not see it because the window is positioned outside the visible display area.

Use the keyboard shortcut Alt + Space, press M, use the arrow keys to move the window onto the main display, then press Enter.

If Move does not appear: Press Alt + Tab to focus the app, then repeat the shortcut. On Windows 11, you can also press Win + Arrow keys to snap the window back or open Task View with Win + Tab and drag it onto the active display.

Another frequent reason is a restriction applied by IT through Group Policy, Microsoft Intune, or Microsoft Entra ID Conditional Access. These rules can block logins based on device, location, or compliance status. In some cases, remote access tools such as Remote Desktop Protocol (RDP) also deny connections if policies or group memberships restrict the account.

Before You Begin

• From the Windows sign in screen, connect to the internet using the network icon or plug in Ethernet, then retry.
• Confirm that you are using the same Microsoft account that is linked to the device if it is a personal PC.
• If this is an organization managed device, your IT policy may enforce the restriction. Contact your administrator if the same message appears on multiple accounts.

Below are solutions to resolve the problem.

1. Check If Your Device Is Remotely Locked

If your device is locked remotely, entering the correct credentials may not progress past the lock screen until the local unlock clears the restricted state. This lock is a security feature designed to prevent unauthorized access when a device is lost or stolen. Clearing the remote lock restores normal authentication and sign in functionality.

1. On another device, open a browser and go to the official Microsoft Find My Device page.
2. Sign in with the same Microsoft account linked to the locked PC.
3. Click the menu (hamburger icon) in the top left corner, then select “Devices”.
4. Locate the locked device and click on Find My Device.
5. Check the status to confirm whether it is locked or unlocked.
6. If status shows Locked, return to the device and unlock on the device using your PIN, password, or biometrics. If the lock does not clear and you remain blocked, open Windows Recovery Environment from the sign in screen, choose Troubleshoot, then use Reset this PC as a last resort.

2. Unrestrict Account via Group Policy

When deny policies are applied to a user, the system blocks interactive logins, RDP access, or network authentication. Removing these deny rules ensures the system recalculates the account logon rights without the restriction, allowing sign in again. Windows enforces effective rights from all applied policies, and refreshing the policy state removes the block.

Use this method when a local or domain policy is blocking sign in. It does not apply to a remote lock scenario.

Note: gpedit.msc and many security policy consoles are available on Windows Pro, Enterprise, and Education. They are not available on Windows Home by default. On domain joined or MDM managed devices, central policy may override your local changes.

1. Sign in to the device with another administrator account.
2. Press Windows + R to open the Run dialog.
3. Type the following command and press Enter:

   gpedit.msc

   

4. In the left panel, navigate to: Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment.
5. In the right panel, double click “Deny log on locally”.
6. Select the affected user from the list and click Remove.
7. Click Apply, then OK to confirm.
8. Repeat this for “Deny log on through Remote Desktop Services” and “Deny access to this computer from the network”.
9. Also confirm the account has the matching allow rights: “Allow log on locally” or “Allow log on through Remote Desktop Services”, and that it belongs to the correct groups such as Administrators or Remote Desktop Users when needed.
10. Open the Start menu, search for CMD, and run it as an administrator.
11. Type the following command and press Enter to refresh group policies:

    gpupdate /force

    

12. If sign in is still blocked, generate a policy report to find which GPO enforces the deny setting:

    gpresult /h C:\gp.html

    Open C:\gp.html and search for the three deny policies to identify the source policy. You can also use rsop.msc to view Resultant Set of Policy.

13. Finally, try signing in again with the affected account.

This can happen after Windows updates, registry conflicts, or interference from third-party software. Below are the most effective solutions to fix this error and restore playback functionality.

1. Disable and Re-enable Media Features

Media Features are built-in Windows components that manage audio, video, and recording functions. Disabling and then re-enabling them refreshes these components, removing potential corruption or incorrect configurations that might be causing the error.

1. Press Windows + R, type optionalfeatures, and press Enter.
2. In the list, find and expand Media Features.
3. Uncheck the box for Windows Media Player.
4. Click OK to apply changes.
5. Restart your computer.
6. After restarting, repeat steps 1 to 3 to reopen Windows Features.
7. Re-check the box for Windows Media Player to enable it again.
8. Click OK and restart your computer once more.

2. Reset Windows Media Player

Resetting Windows Media Player restores it to its default configuration and clears corrupted data, including the media library database. This process forces Windows to rebuild the player’s core components, which often resolves playback errors.

1. Press Windows + I to open Settings.
2. Go to Apps > Installed apps.
3. In the search bar, type Media Player.
4. Click the three dots next to it and select Advanced options.
5. Scroll down and click Reset.

3. Check File Format Support or Install Codec Packs

Sometimes, this error appears simply because the media file format is unsupported by Windows Media Player. Before troubleshooting further, verify whether the file type (e.g., MKV, FLAC) is compatible.

If not, you can install a reliable codec pack like the K-Lite Codec Pack, which adds support for additional file formats. After installation, restart your PC and try playing the file again.

For more information on supported formats, refer to the official Microsoft documentation.

4. Use VLC Media Player as an Alternative

If the issue persists, using a third-party media player like VLC is a practical workaround. Unlike Windows Media Player, VLC uses its own built-in codecs, allowing it to play a wide range of file formats without relying on Windows Media components. This makes it an excellent choice for bypassing issues caused by missing codecs, corrupted settings, or unsupported formats in Windows Media Player.

1. Open your web browser and visit the official VLC website.
2. Click Download VLC to get the latest version for your operating system.
3. Once downloaded, open the installer and follow the on-screen instructions to install VLC Media Player.
4. After installation, launch VLC.
5. Click Media in the top menu and select Open File.
6. Browse to the file that wouldn’t play in Windows Media Player and click Open.
7. Your file should now play without errors in VLC.

Below are the most reliable methods to fix this issue:

1. Enable and Configure the Navigation Pane

The navigation pane can be disabled unintentionally due to a miss-click or system update. File Explorer also includes settings that control how the pane displays folders, drives, and libraries. Re-enabling it and adjusting related options restores its normal functionality.

1. Open File Explorer by pressing Win + E.
2. Click View > Show.
3. Ensure Navigation pane is checked in the dropdown.
4. Close and reopen File Explorer to confirm the pane is restored.

2. Restart the File Explorer Process

If the navigation pane is enabled but still missing, File Explorer may be stuck due to a temporary glitch. Restarting the process reloads its user interface, often resolving such display issues.

1. Right-click the taskbar and select Task Manager.
2. In the Processes tab, locate Windows Explorer.
3. Right-click it and select Restart.
4. Wait for File Explorer to reload, then check if the pane appears.

3. Repair Corrupted System Files Using SFC

If the navigation pane still doesn’t appear, the issue could be caused by damaged Windows system files. The System File Checker (SFC) scans for and restores these files, resolving problems that affect File Explorer.

1. Click the Start icon and type cmd.
2. Right-click Command Prompt and select Run as administrator.
3. Type the following command and press Enter:

   sfc /scannow

   

4. Wait for the scan to finish.
5. Restart your PC and check if the navigation pane is restored.

4. Use System Restore or Reset

If none of the above solutions work, deeper system issues may be preventing File Explorer from functioning properly.

Not sure how to back up your registry? Click here to follow our step-by-step guide on backing up and restoring the Windows Registry.

The ‘Cannot delete (key name): Error while deleting key’ error occurs when the Windows access control system blocks deletion to prevent unauthorized changes. These keys are often protected by the system or owned by TrustedInstaller.

In most cases, this happens because your account does not have ownership or Full Control permissions over the registry key. To fix this issue, you need to take ownership of the key and grant yourself full control permissions, allowing you to delete it.

When you try to delete a registry key, Windows checks the Discretionary Access Control List (DACL) to see whether your account has the required permissions. If not, you must take ownership of the key first and then give your account Full Control permissions. Once these permissions are applied, you should be able to delete the key.

1. Click on the Start button, search for Registry Editor, right-click on it, and select Run as Administrator. 
2. Navigate to the problematic registry key. Right-click on it and select Permissions from the menu.
   
3. In the Permissions window, click on the Advanced button to open advanced security settings.
   
4. In the Advanced Security Settings, click on the Change button next to the Owner field.
   
5. Type your username in the Enter the object name box and click Check Names to validate it. Windows will confirm your username.
   
6. If you are unsure of your username, click on the Advanced button.
   
7. In the next window, click Find Now to list all user accounts. Select your account and click OK.
   
8. Your account will now appear in the object name field. Click OK.
   
9. In the Security Settings window, check the boxes for Replace owner on subcontainers and objects and Replace all child object permissions entries with inheritable permission entries from this object. Click Apply and then OK.
   
10. Click Yes when prompted for confirmation.
    
11. Click OK to close the Advanced Security Settings window. 
    
12. Back in the Permissions window, select your user account from the Group or user names list. In the Permissions for users section, check the Allow box next to Full Control. Click Apply and then OK.
    
13. Once you have ownership and Full Control permissions, try deleting the registry key again.

This error often appears when running older programs that were originally designed for previous versions of Windows, such as Windows XP, Vista, or 7. These programs may not be fully compatible with modern operating systems like Windows 10 or Windows 11, leading to errors like this.

The most common causes behind this error usually include:

• Lack of administrative permissions
• Incompatibility with current Windows versions
• Program blocked by antivirus software (which may prevent it from making necessary registry changes)

Now that you understand the causes, let’s move on to the solutions for resolving this registry update error on Windows 10 and 11.

1. Run the Program as Administrator

Running the program with administrator permissions ensures it has the necessary rights to make changes to the Windows Registry. This step often resolves the error by allowing the program to perform its intended actions. It also helps bypass User Account Control (UAC) restrictions that may otherwise block the process.

Right-click the program that is causing the error and select “Run as administrator“.

To make this setting permanent:

Right-click the program, select Properties, go to the Compatibility tab, and enable “Run this program as an administrator“.

2. Use the Program Compatibility Troubleshooter

The Program Compatibility Troubleshooter is a built-in Windows tool designed to help older programs run properly on newer operating systems. It works by enabling compatibility mode, adjusting display/file settings, and redirecting registry calls for legacy software.

On Windows 10:

1. Open the Control Panel (type “Control Panel” in the search bar and press Enter) and click Review your computer’s status under System and Security.
   
2. Click on Windows Program Compatibility Troubleshooter at the bottom left.
   

On Windows 11:

1. Go to Settings > System > Troubleshoot > Other troubleshooters.
2. Find Program Compatibility Troubleshooter and click Run.

Next:

3. Click Next to begin scanning for programs that require troubleshooting.
   
4. Select the program that is causing the error and click Next.
   
5. Choose “Try recommended settings“.
   
6. Click “Test the program…” to launch it with the new settings.
7. Close the program and click Next.
8. Click “Yes, save these settings for this program” to apply the changes.
   

3. Whitelist the Program in Antivirus

If your antivirus software is blocking the program, it may prevent it from modifying the registry. Adding the program to the antivirus exclusion or whitelist list can help.

1. Open your antivirus settings, navigate to the Exclusions or Allowed Apps section, and add the affected program.
   
2. Restart your computer and try running the application again.

4. Reinstall the Program with Administrator Rights

If the issue persists, reinstalling the program may help. Right-click the installer and select Run as administrator to ensure it has the required permissions during installation.

In some cases, this error also appears in volume-licensed editions when activation servers are unreachable. When triggered, Office switches to a reduced functionality mode, limiting editing and other features until the issue is resolved.

Now that you know the causes, let’s go through the solutions to fix it.

1. Running the OSPPREARM.exe as Administrator (3–5 Times)

The OSPPREARM.exe (Office Software Protection Platform Rearm) is a Microsoft tool that resets the activation grace period and clears any cached licensing data. This can help resolve activation errors caused by corrupted tokens or configuration issues. Running it multiple times (3–5 times) gives Office a fresh start and extends the trial period before you need a valid key.

1. Navigate to your Office installation folder. For Office 2016, the default path is:

   C:\Program Files\Microsoft Office\Office16

   Note: If you’re using Office 2013, 2019, or 2021, this folder will be named Office15, Office17, etc. Adjust accordingly.

2. Locate OSPPREARM.EXE, right-click it, and select Run as Administrator. Repeat this process 3–5 times.
   
3. Reopen Microsoft Word and check if the problem is resolved.

2. Rearming Using Command Prompt

If running OSPPREARM directly doesn’t work, you can do it via Command Prompt. This provides elevated access and bypasses restrictions from background services or antivirus software that may block the tool.

1. Open Command Prompt as an Administrator.
   
2. Type cd\ and press Enter to go to the root directory.
   
3. Navigate to your Office installation folder by typing:

   cd "C:\Program Files\Microsoft Office\Office16"

   and press Enter.
   

4. Type the following command and press Enter to view the current license status:

   cscript ospp.vbs /dstatus

   

5. Finally, run:

   ospprearm.exe

   This will reset the licensing configuration and rearm Office.

   

6. Restart Word and check if the activation error is gone.

3. Permanent Fix: Activate Office with a Valid License

While the rearm process can temporarily restore functionality, it is not a permanent solution. You can only rearm up to five times, after which the trial expires. To fix the issue permanently:

• Purchase a genuine Microsoft Office license or subscription (Office 365/Microsoft 365).
• Sign in with the correct Microsoft account linked to your Office purchase.
• Check your internet connection and ensure your firewall or antivirus isn’t blocking Office activation servers.
• Contact Microsoft Support if your account is licensed but still not activating.

Once properly activated, Microsoft Word and other Office applications will return to full functionality without further errors.
