How to Fix microsoft.build.conversion.v3.5.ni.dll Errors

You do not need to download this file from risky third-party websites. The "ni" in the filename stands for Native Image, which means it is a pre-compiled version of a standard .NET Framework file generated by the system.

Here is how to safely fix it using built-in Windows tools.

1. Turn .NET Framework Off and On

This forces Windows to recreate the missing or corrupted native image cache files.

• Press Windows Key + R, type optionalfeatures, and press Enter.
• Locate .NET Framework 3.5 (includes .NET 2.0 and 3.0).
• Uncheck the box next to it.
• Click OK and restart your computer.
• Open the same menu again, check the box to enable it, and click OK.
• Restart your computer once more.

2. Run the .NET Framework Repair Tool

Microsoft provides a built-in self-repair mechanism for these exact library issues.

• Open the Start Menu, type cmd, right-click Command Prompt, and select Run as administrator.
• Copy and paste the following command, then press Enter: dism /online /Cleanup-Image /RestoreHealth
• Wait for the process to finish, then restart your PC.

3. Clear and Rebuild the Native Image Cache

Since this is an "ni.dll" (Native Image) error, the pre-compiled assembly cache might be corrupted. You can force Windows to regenerate it.

• Open Command Prompt as an administrator.
• Run the following commands one by one, pressing Enter after each: cd C:\Windows\Microsoft.NET\Framework\v2.0.50727 ngen update
• If you are on a 64-bit system, also run these: cd C:\Windows\Microsoft.NET\Framework64\v2.0.50727 ngen update

4. Run System File Checker

This scans all protected system files and replaces corrupted ones automatically.

• Open Command Prompt as an administrator.
• Type sfc /scannow and press Enter.
• Let the scan reach 100% and restart your computer.
