Fix: Oculus encountered an error during installation

Issue:

If you are trying to install Oculus running OculusSetup.exe, but get an error:

“Restart Computer. Sorry, we encountered an error during installation. Please restart your computer and try running Oculus Setup again.”

Repeated Issue:

And even after you reboot, you still face this error…

Check 1:

1. Check your logs:

C:\Users\Abir\AppData\Local\Oculus\OculusSetup.log

Replace “Abir” with your username

2. If you find lines like:

Exception deleting ‘C:\Users\Abir\AppData\Local\Temp\OculusSetup-ff4b833a-8bd3-467b-a5c1-14d1ab58a021’:

System.UnauthorizedAccessException: Access to the path ‘DaybreakNative.dll’ is denied.

Means it needs Admin permissions.

Fix:

1. First delete this folder:

C:\Users\Abir\AppData\Local\Oculus

and

C:\Program Files\Oculus

(Not just the contents.. but the full folders)

It will ask for Admin permission:

This fix will not work if both Oculus directories are not deleted properly.

2. Start installation again as Administrator:

After this, hopefully installation will continue smoothly:

And it should get installed:
