Modern versions of Script Hook V and Community Script Hook V .NET do not support version 1.26. Upgrading to 1.41 allows these essential modding engines to boot without triggering the "Unknown Game Version" fatal error.

Updating from 1.26 to 1.41 often introduces specific technical issues that require the following fixes: Low FPS or Stuttering : Download and install the updated Script Hook V dinput8.dll

: You can use a downgrade patch to revert your game back to a previous version (like 1.0.126.0 ). This is primarily for modders who are willing to sacrifice new features for a stable modded experience and is not recommended for standard gameplay.

Tackling the update from 1.0.126.0 to 1.0.141.0 is about methodical troubleshooting. Start with the basics: verify game files and temporarily remove your mods. If the issue persists, a clean install is your most reliable fix. For the vast majority of players, a simple verification will resolve the issue. Good luck, and enjoy Los Santos!
