Kstudio plugins are used by freelancers as well as in studios of different sizes – from several employees to hundreds.

This feature simplifies the deployment of numerous installations into a large network.

This instruction applicable only for Project Manager

I recommend paying attention to utilities such as PsExec and PowerShell – with their help you can install the 3dsMax plug-ins and apply the license keys in a batch mode.


  1. Download and extract the archive SilentModeInstall.zip
  2. Copy the ZIP archive with the full version of the plugin into one folder with “AutoInstallStart.bat”
  3. Open “AutoInstallStart.bat” and uncomment/add a valid path to 3dsMax.exe
  4. Write activation keys to the file “ActivationActivationKeys.txt”
  5. Run “AutoInstallStart.bat” using PsExec/PowerShell or manually on each computer
Download example: SilentModeInstall.zip

You can use a single identification file to obtain licenses for various plugins.
For instance, you can generate an identification file for Project Manager and use it also in the slot for generating a license for Spline Flow

How to Distinguish Between the Full and the Demo Version You Downloaded and Installed?

Before activation, do not forget to install the full version of the plugin
(the title shouldn’t contain the word Demo)

To determine if you have downloaded and installed the full version or the demo version, here are some key points to consider:

1. Activation: The demo version cannot be activated. If you have downloaded the demo version, activation will not be possible.
2. File Name: The archive containing the demo version will include the word “Demo” in its name.
3. Installation and Launch: During installation or when launching the plugin, the demo version will display the word “Demo” next to the logo.
4. Full Version: If there is no “Demo” label on the logo, but you see the “Demo” label over files, it means you have the full version which requires a license key for activation.
