Lots of settings seem to be in C:\Users\Public\Documents\Keyshot 3 This is a location that is write locked for non-Admin users. I'm guessing a lot of people using Keyshot don't work for a large corporation, but those of us that do must deal with restrictive IT policies. Without being able to write to this directory:
-I can't save any preference settings within keyshot
-I can't import textures, backplates, environments, etc.
-Importing models using coordinates from previous doesn't work
It would be nice to put a warning for this during the install and the option to configure elsewhere (make it a big warning so IT notices it please), or at least place the default setting file to a place where a user without admin-rights can actually write to it.
