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.

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\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\V-Ray\Houdini ##.#.###**
