Hi,
There is no need for any special process - our plug-ins support multiple 3ds Max versions, and the installer should handle the installation process automatically. It might be that for some, 3ds Max 2025 isn't detected by the installer. When installing, in the Select Installation Type window, please check the Advanced Installation option - that will enable the selection of versions that aren't "detected" (in this case, 3ds Max 2025).
I hope that helps you, and please let us know if everything is working fine or if you are still facing trouble with it. Thanks in advance and have a great day.
Best regards,
