This page provides information on setting up V-Ray through a silent installation and removing V-Ray through a silent uninstall.


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 file 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_60ххх_max20nn_x64.exe -gui=0

Follow the instructions and set up the installation 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

In the second step, run the installer with the following command:

vray_adv_60004_max2023_x64.exe -gui=0 -configFile="xml_file.xml" -quiet=1 -auto


The -quiet=1 argument causes the installer to read the variable values from the .xml file and does the installation without user input. If you do not specify the -quiet=1 option, the installer asks for a confirmation of each variable before proceeding.


Configuration File

The config.xml file holds configuration information about the settings of the installation. Below is an example of such a config file.

Below is a description of the variables of the installer:



Specifies whether or not the installation uninstalls previous version:

1 – Uninstalls previous version

0 Skips the uninstallation of previous version


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.


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.

Specifies the root folder of 3ds Max.
Specifies the destination folder for V-Ray additional files (tools, documents, samples, libraries and uninstall information)

Specifies the plugins folder for 3ds Max; the default places it as a sub-folder of the 3ds Max root one.

Specifies the destination path where shortcuts are placed.
Specifies the destination folder for V-Ray common files.

Specifies whether or not to open the V-Ray online documentation after the installation is complete.

1 Opens the V-Ray online documentation.

0 Does not open the V-Ray online documentation.


Tt is the only variable that controls the increase in tdr delay.

For huge scenes it may take longer time to export and prepare the GPU for rendering. Usually drivers automatically stop the process if there is no response in a small amount of time and report the application as not responding. To avoid this, we change the default delay of the drivers to 8 seconds.

0 The installer does not make the change of the delay.

1 The installer makes the change of the delay.


Specifies whether or not to open the Change Log once the installation is complete

1 – Opens the Change Log.

0 – Does not open the Change Log.


Specifies the installation type:

0 – Workstation

1 – 3ds Max render server

2 – Standalone render server

3 – License server only

For a complete description of each installation type refer to the Installation of V-Ray section.


Corresponds to the Register V-Ray menus toolbar functionality.


Controls whether the user feedback system is used.

0 Makes 3ds Max ask on its own upon startup

1 Enables the feedback program

2 Disables it for all users, except those who have explicitly enabled it from 3ds Max itself.


This section specifies the client license settings.


Primary license server's IP Address


Alternate license server's 1 IP Address


Alternate license server's 2 IP Address

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:

<STDROOT>\uninstall>installer.exe -uninstall="<STDROOT>\uninstall\install.log" -uninstallApp="V-Ray 6 for 3ds Max ####" -auto -quiet=0


  • <STDROOT> is the V-Ray installation directory;
  • #### is the version of 3ds Max;
  • -quiet=0 is used to display the output of the silent uninstall in the console and can be omitted.
