When I want to run a Creo Parametric 2.0 it shows me next text: "Windows needs the file parametric.exe", and suggest me to show the way to this file. It must be in C:/Program Files/PTC/Creo 2.0/Parametric/bin but isn't there. Also there are another files called parametric, but only parametric.psf and parametric.bat. Parametric.exe is missing. I've already reinstalled it more than 3 times and it doesn't help.
