Extract the UEVR.zip to a folder of your choice, then:
- Launch the frontend GUI (UEVRInjector.exe)
- Launch the target game
- Locate the game in the process dropdown list
- Select your desired runtime (OpenVR/OpenXR)
- Toggle existing VR plugin nullification (if necessary)
- Configure pre-injection settings
- Inject
More information and troubleshooting can be found on the Documentation page.
You may need to whitelist the UEVR folder or executable within your antivirus software for the time being.
If nothing happens, try moving UEVR to a different folder.
