--- title: "Portable Installation" canonical: "https://documentation.chaos.com/space/VBLD/117639082/Portable%20Installation" format: markdown --- This page provides information on the V-Ray Portable installation. Please do not use multiple V-Ray installation methods at the same time. If you plan on creating a Portable V-Ray installation for Blender, make sure you have uninstalled any other V-Ray version for Blender. Overview The V-Ray installer can be unpacked and used as a portable version. Creating a Portable Installation provides several advantages over the regular installer: The Portable installation allows for setting a custom environment when starting each Blender instance. To compare, running the regular installation multiple times overwrites the V-Ray environment variables . The Portable installation can be used to run V-Ray for Blender and V-Ray Standalone from any location or even a network drive. That way, multiple users can start Blender along with V-Ray using just a script that sets up the environment variables without the need to run local installations. Upgrading a Portable installation is a lot easier, as you don't need to run the installer on every user's computer. The Portable installation allows for quick switching between different V-Ray versions without reinstalling it. To use the Chaos Unified Login (a single login into whichever Chaos application grants access to all Chaos applications) with V-Ray portable installation, download  and install separately.  When using V-Ray from a Portable installation, the EULA needs to be accepted to start a render. A pop-up window will prompt you to accept the EULA the first time you start a render. Batch rendering is an exception to this. Required steps to run V-Ray To create a Portable installation, you need to: 1. Download V-Ray. 2. Unpack the installation file. See the Unpack the installation file section of this page for more information . 3. Set up the environment variables needed to run V-Ray for Blender. 4. Activate your license. Visit the Activate your Product page to find out how. 5. Run Blender. Unpacking the installation file Unpack the installation into a suitable location, which you can later use to run V-Ray on any computer. Here is a detailed step-by-step guide: Download the V-Ray installer executable (.exe). Open a Command Prompt. Type out: the location of the installer that you just downloaded -unpackInstall= location where you wish to unpack. Alternatively, you can drag and drop the installer and a target folder for unpacking into the Command Prompt to insert their directories. Press Enter to run the command. As an example, you can create a new folder called vray_builds to hold all portable V-Ray builds. Then, you can make other sub-folders and name them according to the V-Ray build version, for example vray_adv_62000_blender410_x64. It should look something like this: D:\Downloads\vray_adv_70000_blender430_x64.exe -unpackInstall=D:\vray_builds\vray_70000_blender430 After unpacking the installation, your folder structure should look like this: D:\vray_builds\ ├── vray_70000_blender430\ │ ├── blender_root\ │ ├── blender_vray\ │ └── vray\ The D:\vray_builds location is an example. The Portable Installation can be placed anywhere. 3. Set the necessary environment variables in a new Command Prompt and run V-Ray for Blender. License setup 1. Before you run V-Ray, make sure that it can find a license. You can set up your license using the tool to set or change your license settings. Alternatively, you can use the VRAY_AUTH_CLIENT_FILE_PATH *  environment variable and point it to the folder containing  a  vrlclient.xml   file that holds the V-Ray license server settings (IP address and port number). When using the environment variable is the best option for you and you need to create the  vrlclient.xml   file manually, the example below shows what it should contain: Example: vrlclient.xml 10.0.0.100 30304 30304 30304
