I use LINUX as my primary operating system, including Aces High Version 2.12.4. (about 1.5 years old now). I tried to get a newer version of Aces High running under LINUX, but it gave me some trouble and I lost interest, since I also have Windoze systems that support it well. I suspect it could be done using some variation of the approach I used.
I published EXACT, full details of what I did to switch to LINUX from Windows, using Aces High as the most advanced target application, here:

One problem: I have never been successful getting the Mission Editor to run under Linux, so I use Windoze for that too.
I hope this helps!
