Thanks, dimesio. I upgraded to the latest version, and after a couple of tries msxml4 installed using winetricks with no errors. Now my MathCAD install gets a bit furthur before spitting out the error: Code: err:ole:xCall RpcChannelBuffer SendReceive failed, 8001010e err:richedit:ReadStyleSheet ReadStyleSheet: skipping optional destination but that might be a problem specific to my ripped copy of MathCAD 14. I guess it's time to learn about virtual machines. Yar
