This page provides details on the uninstall process for V-Ray in Revit.

Uninstall

The V-Ray installer automatically uninstalls any previous versions.

If you need to manually uninstall V-Ray, make sure that Revit or V-Ray components are not being used.

Then open the Windows Start Menu > Chaos Group > Uninstall V-Ray for Revit or alternatively run C:\Program Files\Chaos Group\V-Ray\V-Ray for Revit\uninstall\Uninstall.lnk.

This starts the V-Ray uninstaller. Follow the on-screen instructions to remove V-Ray from your system and restore any files overwritten by the installation.
