Weird... their 6.1 Release AutoBackup claims "Missing license file" in the very first popup dialog, and the only button I can click is "I disagree", then it closes. The rest work, with varying degrees of difficulty, in Wine though. They still haven't fixed the obvious leaks in the code though. Nice.
Update: NONE of these Simulators from 6.0 through 6.0.1 and 6.1 run on Windows 2000, XP and 2003, on clean systems with the latest service packs and patches. They're all missing core modules, and they error out:
You can see the errors in the screenshot montage here:
