I notice that if you go to the license manager (using the pulldown) the option to convert is disabled. I seem to remember that there was a file that could be deleted, then when Rhino was re-started there would be a window to enter the keycode.
Can someone remind me of where that file is, or better yet, a more elegant way to do the conversion?
It probably should be noted, however, that having that “Convert” button functional when going from the Zoo to a stand-alone license would probably be a good idea.
