Fix32 OS Requirements

Hey guys, what is the latest and most stable OS supported by Fix32 Version 7.0? I need to build a development box to do some testing with Fix32 and want the most reliable/stable environment I can create.

What is the latest OS, SP etc that I should be looking at installing on my Dev Box.

Thanks.

I have run FIX32 on Windows NT , Windows 2000 and Windows XP SP2.
All of which worked just fine.

Ok Cool, so there are choices. Among the three NT, 2000 and XP SP2 is there a preferred or will it run equally as smooth on all 3 OS's.
