Error: godot unable to load .net runtime

Solution

What's Causing This Error

The error 'godot unable to load .NET runtime' typically occurs when Godot Engine, which supports C# thanks to its integration with the .NET framework (specifically Mono), cannot find or initialize the required .NET runtime environment on the system. Causes can include:

• Incorrect or Missing .NET SDK/Runtime: The most common cause is that the .NET SDK or runtime required by Godot is either not installed or an incorrect version is installed.
• Wrong Configuration: The build configurations might be set incorrectly, pointing to a non-existent .NET runtime.
• Corrupted Mono Build/Installation: The integrated Mono version within Godot could be corrupted or improperly installed.
• Path Environment Variable: There might be an issue with the PATH environment variable not including the location of the .NET runtime.
• Operating System Compatibility: The operating system might not be compatible with the version of Mono or .NET used by Godot.

Solution - Here's How To Resolve It

To resolve the 'godot unable to load .NET runtime' error, follow these steps:

1. Install the Correct .NET Version: Ensure that the correct version of the .NET SDK/runtime is installed on your machine, as specified by the Godot documentation for your version of the engine.

3. Verify Project Settings: In Godot, check the project settings under Project > Project Settings > Mono and ensure they're correctly configured for your setup.
4. Update Environment Variables: Make sure that the PATH environment variable includes the directory where the .NET runtime is installed.
5. Reinstall Godot/Mono: If all else fails, try reinstalling Godot with Mono support or repairing your Mono installation.
