Tried reinstalling, didn't work. Then deleted all PTC and reinstalled didn't work. Restored computer to before deleting QA, now the box pops up that says PTC Creo Parametric Student, disappears but nothing starts. Tried with the other programs too.
I followed the instructions on Creo 2.0 - Student Edition – Quick Installation Guide both times. Before part files would show as only the standard icon, but now they look exactly as they did before, like the real part. Tried from the bin folder and running as admin.
