Many Windows applications work great, but some might have reduced functionality, or possibly not run at all. This translation system means you don't need to spend hours setting up Windows OS first, you can just install your Windows application directly into CrossOver and run it.īut it's a big process to try and recreate all the Windows OS commands, and CrossOver isn't complete yet. Unlike an emulator that requires a full copy of the Window OS, CrossOver translates the commands your Windows application wants to use to your installed OS and back.
