I've got a problem with Creo 3 Academic version. We have PCs that have been running Creo 2, and tried to install Creo 3 over the top. Creo 3 seems to install with no errors, however the program will not launch.
I've uninstalled all of Creo 2 and 3, deleted the Program Files and ProgramData directories, as well as the HKLM/Software/PTC registry key. Following that and a restart, I've tried reinstalling Creo 3, again installed with no errors, however the program will still not launch, and doesn't throw up an error message, or log anything in the event log.
Using the same installation files on a clean PC (i.e. never had Creo installed), the software launches successfully.
Any hints as to why the program fails to launch, or are there some other hidden files I need to delete first?
Thanks in advance
