Support for Space Navigator 3D Mouse?

,

Thanks for the excellent space mouse plug-in!. I will be more than happy to buy it for every member of our team when you get it on the marketplace. It really increases ease of navigation and productivity.

I am using UE 4.26 and get this message unless I place the two directories in the project folder:

Also the custom key mappings does not seem to work. I tried to set button 1 to key F, for fast asset centering, and does not seem to work. I am using the basic 2-button 3D mouse.
Thanks again
