Philip,
Can you run in XP compatibility mode? I can't get it to run on my machine, and I think it's because that requires administrative privileges on the license server which I haven't figured out how to set. The kludge of dropping the XP version of opengl32.dll into the Mathcad directory seems to be working fine with everything as I can't find any other Mathcad stuff using opengl, but that requires a video driver that will support deprecated opengl as well as not wanting to use anything in Mathcad that needs current opengl support.
