Creo 4 mechanica, fails to run with an error "The license to run engine is not available" even though they have a license.
Do you have these lines in your license file?
#MECSTRUCENG_STSIM 2 Pro/MECHANICA STRUCTURE ENGINE Creo 4.0 Flt Lic perm
#MECSTRUCUI_STSIM 2 Pro/MECHANICA STRUCTURE UI Creo 4.0 Flt Lic perm
#MECTHERMENG_TH 1 Pro/MECHANICA THERMAL ENGINE Creo 4.0 Flt Lic perm
#MECTHERMUI_TH 1 Pro/MECHANICA THERMAL UI Creo 4.0 Flt Lic perm
We just re-did our licensing for Creo 4 and a lot of things changed, in particular the Simulate entries. The latest license file I got from PTC had the following lines (omitting the "Contract" column)
#MECBASICENG_License 1 Creo Simulation Basic ENG (formerly Pro/ Creo 4.0 Flt Lic 29-oct-2018
#MECBASICUI_License 1 Creo Simulation Basic UI (formerly Pro/M Creo 4.0 Flt Lic 29-oct-2018
This stuff is never fun.
I did and it they were the same.
Strangest thing: User who reported this said it was working fine the following day. Not sure what changed; reboot, hung license maybe.
next time please run ptcstatus.bat to see whether Simulate license is free. If it is in use without reason, then restart license manager to free it.
