Creo 7 crashing after downloading Creo 11

Hi everyone,

 

I recently downloaded Creo 11 on a machine with Creo 7 in order to test something. After deciding to test on my virtual machine, I uninstalled Creo 11. I now get this error in Creo 7:

When checking the logs, the error reads: EXCEPTION_ACCESS_VIOLATION has occurred in the thread 3772. I've tried clearing cache and reinstalling. Any ideas?

You will probably need to open a helpdesk call with PTC to resolve this issue. 

The community is users helping users and we do not have access to things like Traceback error codes.

Hi,

  • uninstall Creo 7
  • remove Creo 7 installation directory (if it still exists)
  • remove %APPDATA%\PTC directory
  • install Creo 7
