We recently updated from Creo 3 to 4. While Creo 3 worked like a charm (and still does), Creo 4 started acting up after a couple of days and it now becomes unresponsive after just a few modeling steps. That's the same issue on Windows 7 and 10 workstations, the driver for the graphic adapter are up-to-date (NVIDIA Quadro). All config options were deactivated. Any suggestion is welcome.
to test whether the problem is related to graphic card drivers, please add following option to config.pro file
I checked this already. It's definitely not the graphic card driver.
Any other idea? Did anything change between Creo 3 and 4 how it deals with firewalls? What I mean is- is there an ongoing communication between the license server and local machines?
another try ...
1.) create new empty directory with full access for your user account
2.) add following line at the end of parametric.psf file in Creo 4.0 installation
Guess: Maybe some config option causes the problem...
just tried this. Creo created the folders .settings, .ssappd and .ssrd after starting. So that appears to be working. But it still freezes on me, interestingly enough even faster than before. It appears that the number of steps until Creo stops responding is decreasing after every new program start.
Btw- I initially suspected config options, which is why I disabled the config.pro entirely.
Another thought- our company uses a customized version of Michal Trojnara's stunnel software- supposedly for TLS encryption, but Lord only knows what else it does. The floating Creo licenses are stored on AWS, could there be any communication issues?
if you want to eliminate a communication problem, you can borrow Creo license ... this means to start Creo using parametric_borrow.bat
Unfortunatelly license borrowing has its own rules and your environment must be prepared for using it.
