Does anyone know if CS5.5 for Windows is working in CrossOver for Mac?
Ideally, it should but its a sort of virtual environment, so, it may or may not work as we have not tested it on that environment.
The best way to do it is to Upgrade your current CS 5.5 to CS 6 and get Multi Platform Keys. You can then Choose any, WIN or MAC to install the CS. If you need and support please let me know.
