Downloaded Creo 3.0, cannot find parametric.exe

Hey guys,

I downloaded the Creo 3.0 as a university student for free for my 64bit processor. After installing, I was unable to open any of the applications because the execution files simply were not there. I reinstalled multiple times, the common files were installed, nothing seemed to go wrong during the process, but when I tried to open any of the applications a window popped up saying the files were not found. Please help.
