The uiautomationtypes.ni.dll error usually happens due to corrupted .NET Framework files or registry mismatches. You can fix this issue without downloading anything by using built-in Windows repair tools.

1. Run the Deployment Image & System File Checker

Windows has native tools to automatically replace missing or corrupted system DLLs.

• Press Windows Key + X and select Terminal (Admin) or Command Prompt (Admin).
• Type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter.
• Wait for the process to finish completely.
• Type sfc /scannow and press Enter.
• Restart your computer.

2. Repair the .NET Framework optimization cache

The .ni.dll extension means this is a "Native Image" generated by the .NET Framework. Resetting this cache fixes most compilation conflicts.

• Open Command Prompt (Admin).
• For 64-bit systems, type cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319 and press Enter.
• For 32-bit systems, type cd C:\Windows\Microsoft.NET\Framework\v4.0.30319 and press Enter.
• Type ngen update and press Enter to compile and repair native images.

3. Re-register the DLL file

Manually registering the file forces the Windows Registry to recognize the library correctly.

• Open Command Prompt (Admin).
• Type regsvr32 /u uiautomationtypes.dll and press Enter to unregister it.
• Type regsvr32 uiautomationtypes.dll and press Enter to re-register it.

4. Turn .NET Framework features off and on

Toggling the feature resets the files associated with User Interface Automation components.

• Press Windows Key + R, type optionalfeatures and press Enter.
• Locate .NET Framework 4.8 Advanced Services (or your current version).
• Uncheck the box and click OK.
• Restart your PC.
• Reopen the same menu, check the box again, and click OK to reinstall it locally.
