PROTEL 99SE WINDOWS 7 64 BIT LIBRARY PROBLEM PC
Virtual PC aka "XP Mode" works (all this from fairly quick tests obviously) but is vastly slower than native so might as well stick with a 5 year old PC if you want to use Protel 99SE. Virtualbox has nasty redraw delays making it unusable for anything with polygons (fast until it reaches a certain track limit then it freezes repeatedly during redraws). Screen redraw faster than native I think (another Win 7 problem?).

Sorry I can't help, other than to say the lastest version of VMware Player worked quite well with Protel in Windows 2000 / etc except for a small annoying mouse click delay. That's an eye opener - had I known that I would have made the decision to downgrade Win 7 much earlier and saved myself a lot of time! Protel was one of the first apps I checked as it's a "must work" for my job, I obviously didn't go deep enough. Make a new DDB - locks up and can't go any further. Of course it loses all my settings (or rather recreates them from scratch as above). (Another reason to downgrade Win 7 to XP.) Damn, same error you get when loading libraries, can't go any further. Interested so trying it now on my new (but useless) 8 core machine - I'm an administrator, but UAC enabled. A nice idea, but Windows' implementation is a little flawed - if you then execute the app "as administrator" to solve some compatibility issue, then it forgets about the files in the virtual store and recreates them in \windows or wherever.

I installed it with UAC enabled, which redirects all the silly files Protel puts in the windows directory to the virtual store. Yes, I am administrator, I can't remember if it asked for admin priveledges when installing, I don't think so.
