When you install the Oculus app on your PC computer, it'll install on the C: drive. If you want to install the app on a different system drive, make sure the new system drive has sufficient free disk space and is formatted to use the NTFS file system.

To install the Oculus app on a different system drive:

1. Press the Windows key> + R to open the Run command
2. Enter the following path: [drive]:\Users\USERNAME\Downloads\OculusSetup.exe /drive=[new system drive]
   - Replace [drive] with the letter of the drive where Oculus was downloaded to
   - Replace [new system drive] with the letter of the new drive you'd like to install Oculus to
   
   Ex: C:\Users\USERNAME\Downloads\OculusSetup.exe /drive=D or C:\Users\USERNAME\Downloads\OculusSetup.exe /drive:D
3. Click OK

The Oculus app will then open and attempt to install the app on the new drive you've chosen.
