Alan,
PROE_FoundationAdv license contains ASSY_PERFORMANCE module. This license enables you to create SimpRep in ASSY.
PROE_Foundation license does not contain ASSY_PERFORMANCE module. This license does not enable you to create SimpRep in ASSY.
Test:
Launch Creo and click File > Help > System information.
In License Information section check License Name line.
If it contains PROE_FoundationAdv, then you can create SimpRep in ASSY.
Your parametric.psf contains the following line:
ENV=CREOPMA_FEATURE_NAME=PROE_FoundationAdv PROE_Foundation ()
This means that Creo tries to get PROE_FoundationAdv license during startup. If PROE_FoundationAdv license is in use, then Creo automatically tries to get PROE_Foundation license during startup. If PROE_Foundation license is also in use, then Creo informs you that there is no free license.
Try to change the above mentioned line to the following one:
ENV=CREOPMA_FEATURE_NAME=PROE_FoundationAdv ()
After this change you will always launch Creo with the proper license.
