I get the same thing with my copy of TurboCAD V19 Deluxe (126.96.36.199). I get the Splash Screen with "Open/Cancel/New", but "Open/New" don't work. I use the "New/Open" icons to open the "New TurboCAD Drawing" dialog or the "File / Open" dialog.
I tried dumping the Built-In folder contents, doing a Repair, changing the Compatibility to Win 7, and Run as Administrator; nothing worked. I guess some Windows Update wrecked something.
EDIT: You could delete or rename the "TCStart.exe" file with an OLD extension; TCStart.exe.OLD. You'll skip the Splash Screen, then go to "File / New or Open". It removes a step.
