Ah. Okay, that makes sense. Fortunately, the software I’m looking at is available for Mac OS X.
(Nitpick: Crossover is not vertualisation software; it provides Windows services to programs without Windows being involved at all. As such, it’s only tested to work with a limited prange of programs, and specific vesions at that.
You can try other Woindows or even DOS programs with Crossover, but it’s pretty much hit and miss. I tried HP’s communication software for the HP48 calculator, which dates from the early nineties, and it didn’t work.
Parallels and Fusion are full virtualisation environments; they provide virtual machines on which you install Windows, then your desired Windows software. Not having used either, I don’t know the specs of the virtual machines; i’m not surprised if they don’t include high-end hardware.)
