User Account Corrupted

If some apps can’t start with this error code, it’s usually caused by a corrupt user account. The best way to solve this problem is to do a Clean Boot and run the application again.

In Clean Boot, Windows disables all third-party applications and services. This will help ensure that the problem is not caused due to interference from these apps and services.

How to Perform a Clean Boot

It’s simple, just follow these steps:

  • Log in to your computer as Administrator
  • Press Windows + R, type msconfig and press enter. Alternatively, you can also search msconfig in the search box and choose System Configuration.
  • In the System Configuration window click on the tab Services, choose Hide all Microsoft services and then click Disable all
  • Click on tab Startup on System Configuration and click Open Task Manager.
  • In Task Manager, open tab Startup and select each service and click Disable (located in the lower right corner).
  • Closed Task Manager and return to the window System Configuration. Click OK.
  • Restart your computer or Reboot.

After rebooting, try launching your app again and see if it works. If it launches successfully, it means the error was caused by a third party app or service.

Create New User Account

If a clean boot doesn’t help, there’s one more thing the user can try. Create a new user account in Windows and try running the application again.

To do this, just follow these steps:

  • Click Start and open Settings, then select Family and Other Users.
  • Click Add someone else to this PC.
  • choose Add a user without a Microsoft account.
  • insert credentials.

After creating a user account, Login using that account and see if the app works. If not then it’s time to move on to another method.

Reinstall DirectX, Redistributables, and .NET Framework

A common fix for many issues faced by users is to reinstall DirectX, redistributable packages such as Microsoft Visual C++, and .NET Framework. The reason is that some applications, especially games, require the latest versions of the tools and libraries mentioned above to run properly.

SFC or System File Checker is another nifty feature included in Windows. This program checks files system missing or damaged and fix it.

How to use SFC? Just follow these steps:

  • Launch Command Prompt as administrator.
  • To verify and repair system files use sfc /scannow.
  • To verify system files, use sfc /verifyonly. (No changes made to system files and DLLs)
  • Press enter.

If SFC finds an error and fixes it, try running the affected program again to see if it works. There may be instances where SFC will find a corrupted file but won’t be able to fix it. In such cases, it is best to run the program once or twice.
