Issue:

How to repair or reinstall the Microsoft .NET Framework to correct a problem with the installation or running of Autodesk software, such as a "general failure" during installation (due to a conflict with installer prerequisites) or any type of misbehavior or crash during normal operation.

Environment:

Windows operating system (OS) only. Only the Windows OS uses the .NET Framework.

Causes:

For Windows 8, 10, or 11

  • Outdated OS and .NET Framework.
  • The only method is to repair .NET Framework and to run the System File Checker. The .NET Framework cannot be uninstalled on Windows 8, 10, or 11.

 

The .NET Framework can be reinstalled from Windows 7 and older OS.

It will show up in Programs and Features (Add or Remove Programs for Windows XP) amidst the list of installed programs.

Solution:

For Windows 8, 10, or 11

  1. Update the OS, it will automatically look for and install missing updates for the .NET Framework.
  2. Download and run the Microsoft .NET Framework Repair Tool.
Then run the System File Checker:
  1. Launch Command Prompt using "Run as administrator" from Windows. 
  1. Type in the command: "SFC /SCANNOW".
  2. Wait for it to finish and view the message that is displayed:
    • No corruptions with .NET if message is: "Windows Resource Protection did not find any integrity violations."
    • Corruptions repaired if message is: "Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log." Test the Autodesk software again to see if the issue is now resolved. 
    • Refer to Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support if message is: "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log." The OS may need to be reimaged to resolve the issue. 

 

The .NET Framework can be reinstalled from Windows 7 and older OS

For older Windows operating systems:

  1. Open Programs and Features from the Windows Control Panel (or Add or Remove Programs for Windows XP). An easy way to bring this up on non-Windows XP systems is to type "programs and features" in the search field at the bottom of the Start menu.
  2. Uninstall everything that starts with "Microsoft .NET," removing newest versions first.

  3. Download and install the latest .NET runtime version for the applicable OS from: Microsoft .NET Framework.
