creo parametric 1 license problem

Hi there. I have a problem with my creo parametric 1 schools edition.

I downloaded and installed the file, as well as generated a license-file.

However when I open the program it pops up with a license error message, to which i can only reply "ok". Then it closes.

WHat should i do? I tried removing the program but there is no uninstall function and the program doesnt show in control panel either.

Really sad situation for me

I have a totallynew pc that easily can run creo as well as win64.

hope for help.

thanks,

Anders
