This page provides information on setting up V-Ray through a silent installation and removing V-Ray through a silent uninstall.
Overview
A silent installation allows you to complete V-Ray installation without user input during the process using a predefined set of options. To set up a silent installation, you need to perform two steps: creating an .xml configuration file that stores the installation parameters and running the installer.
You can remove V-Ray from your machine similarly through a silent uninstall.
Creating the .xml file
Run the installation file from the command prompt with the -gui=0 argument.
vray_adv_xxxxx_max20xx_x64.exe -gui=0
To suppress the full console output and speed up the generation of a config file, add the -quiet=1 argument.
vray_adv_xxxxx_max20xx_x64.exe -gui=0 -quiet=1
Follow the instructions of the installation and set it up the way you want to have it on all machines. This creates a file named config.xml in the folder of the installation file.
Running the installer
Once a config.xml file is generated, you can use it to pass the installation parameters to the installer on any machine in an automated way:
<code data-v-c2b1f83f=""><span data-v-c2b1f83f="" class="line">vray_adv_70001_max2025_x64.exe -gui=0 -configFile="config.xml" -quiet=1</span></code>
Configuration File
The config.xml file configures the automated installation. See the config file for your 3ds Max version:
3ds Max 2022 and later

This table describes of the common variables that can be defined in the .xml file:
SHOULDUNINSTALL | Specifies whether or not the installation uninstalls previous version: 1 – Uninstalls previous version 0 – Skips the uninstallation of previous version |
SHOULDUNINSTALL | Specifies whether or not the installation uninstalls previous version: 1 – Uninstalls previous version 0 – Skips the uninstallation of previous version |
REMOTE_LICENSE | Specifies whether the V-Ray license server runs locally or on another machine. 0 – The license server runs locally on the same machine. 1 – The server is on a different machine in the network. |
REVERT_INSTALL | The parameter is used when the installer encounters an error – it triggers uninstallation and removes the files that have been populated before the error appears. Should always be set to its default 1. |
MAXROOT | Specifies the root folder of 3ds Max. |
STDROOT | Specifies the destination folder for V-Ray additional files (tools, documents, samples, libraries and uninstall information) |
PLUGINS | Specifies the plugins folder for 3ds Max; the default places it as a sub-folder of the 3ds Max root one. |
STARTMENUPROG | Specifies the destination path where shortcuts are placed. |
COMMONFILES | Specifies the destination folder for V-Ray common files. |
ANONYMOUS_TELEMETRY | Specifies whether to enable telemetry for the most used product functionality and/or parameter values. The data is not personally identifiable and is not tied to the user's individual account: 0 - Anonymous telemetry is disabled. 1 - Anonymous telemetry is enabled. |

Silent Uninstall of V-Ray
Use silent uninstall to remove your V-Ray installation without the need for user input during the process. The silent uninstall uses a predefined set of options.
V-Ray for 3ds Max can be silently uninstalled from a console with the following command line:
<code data-v-c2b1f83f=""><span data-v-c2b1f83f="" class="line">C:\Program Files\Chaos\V-Ray\3ds Max 2025\uninstall\installer.exe -uninstall="C:\Program Files\Chaos\V-Ray\3ds Max 2025\uninstall\install.log" -uninstallApp="V-Ray 7 for 3ds Max 2025" -quiet=0</span></code>
Where:
- -quiet=0 is used to display the output of the silent uninstall in the console and can be omitted.
