Troubleshooting Steps

If you’re still having issues, here are a few things you can try:

  1. Follow the instructions located here to completely reinstall VRChat

  5. Check to make sure your anti-virus is compatible with EAC by referring to the Compatibility Guide listed here and that any firewalls you may have enabled aren't blocking Easy Anti-Cheat

 

Other Known Fixes

  • Commonly known software conflicts - While not always being the root cause, disabling or temporarily closing some of the following applications has helped in previous cases:
    • AVG
    • iCue by Corsair
    • Asus Armoury Crate
    • Avast
  • Windows Updates - Make sure that you are running the latest version of Windows available to you, and check for any available updates (including any Visual C++ Redistributables)

  • Update Graphics Driver - Make sure you're running on the latest driver updates available for your GPU

  • Scan for Malware - Scan for any malware, as there may be malware that could be interfering with EAC's functions

  • Restart your PC - Make sure that you try restarting your entire computer fully to restart any services that may be required to function alongside EAC

 

Once you’ve completed the above steps, restart your computer entirely, and then try running VRChat again. If issues continue, send in a support ticket with a screenshot of any error messages that appear or include a quick recording of the experience.
