This page provides information on how to uninstall V-Ray using the included V-Ray uninstaller.
Overview
The V-Ray installer automatically uninstalls any previous versions before installing a newer version. If you need to manually uninstall V-Ray, please make sure that Houdini or V-Ray components are not being used. For silent uninstallation, see the Silent Uninstall page.
Note that uninstalling V-Ray from Houdini does not uninstall Chaos License Server. It can be uninstalled separately, if needed.
Windows
The Uninstaller originally resides in the following location - C:\Program Files\Chaos Group\V-Ray\Houdini ##.#.###\uninstall
To access the V-Ray uninstaller from the Start menu, search for Uninstall V-Ray Houdini ##.#.###.
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.
After the uninstall is complete, there may be some leftover files that you need to delete.
Please check if present and delete the following files and folders:
C:\Program Files\Side Effects Software\Houdini ##.#.###\vray
C:\Program Files\Chaos Group\V-Ray\Houdini ##.#.###
