How do I get my C4D license in 25/26 to register it for reaction? No matter what I do it wont activate. It’s activated on R21 but I don’t use that anymore and Things have changed since Maxon One.

I’m having issues installing 0.2.8. I get the following error:
It won’t let me uninstall 0.2.7 either. I get the same error.

I did copy reaction plugin to R26 when it was released. I’ve tried removing it and then installing/uninstalling but it doesn’t work.

Reactions should ask you for your login on startup unless it’s already activated. The login is independent of your C4D license.
Does it not activate when you enter the login or does neither the login window nor the plugin appear in C4D?

This problem is most likely caused by a bug in an earlier installer that did not clean up properly. Please try the Microsoft tool linked below to clean up the installation. Then try installing again.

Can this version work without the need for an NVidia driver? I want to test the standalone version only through a CPU. When I start it, an NVidia driver message appears. Thanks in advance!

I’m using a Radeon GPU.

Not yet. The Nvidia driver will be fully optional in one of the next updates.
