Jim.. what your installer should include is "restoreSCR.reg". Or at least an option to have it merge. Or.. have it available as a download from the same page as your SS. Or.. as other screensavers seem to do is rename the shortcut to an *.exe.
Autodesk programs continue to take control over *.scr type of files and thus on a computer that has an Autodesk application installed your SS will not run from the shortcut your installer places on my desktop.
