  • Corrupted Download Files
  • Leftover Installation Data
  • Permission Restrictions
  • System Interruptions or Crash

How to Fix CRC Error When Installing NVIDIA Drivers on Windows 11

Before you do anything else in this guide delete the current file you have on your comptuer, then go to the official NVIDIA driver page and download the same version again. Make sure that it fully downloads, some browsers may block downlaods requring a final confirmation before they land on your PC so check that as well.
