Errors related to Microsoft .NET Framework are quite common, especially when running various applications or games on Windows. The message "Failed to initialize .NET Framework" can appear for a variety of reasons, from corrupted system files to the absence of the required .NET Framework version. In this guide, we’ll go over the common causes of this issue and provide step-by-step solutions to get your programs working again.

1. Check the Installed .NET Framework Version

One of the most frequent causes of this error is a missing or incorrect version of .NET Framework. Here’s how you can check which version is installed on your computer:

If the required version is missing, download and install it from the official Microsoft website: Download .NET Framework.

2. Run System File Checker (SFC) Scan

The issue might be caused by corrupted system files. You can use the built-in System File Checker tool to scan and repair these files:

  3. Wait for the scan to complete and then restart your computer.

This command will automatically detect and repair corrupted system files, potentially resolving the .NET Framework error.
