Howdy, Larry! Long shot, but right click on the executable for the workstation installation and change the emulation mode to Windows XP. That's ""usually"" worked for me on 3.71 in later Windows versions, but I haven't installed it on 2012, just 2008. 2012 is when Microsoft got serious and pretty much rewrote the server OS from the ground up. A lot of older software will simply not work on it any more. In some cases I've had to run them in VMs using older an older OS.
