Is it confirmed that in CREO 7 the GCRI methodology is not supported anymore ?
I can't find the "readnewermodels.dll" file.
Correct. Because multi-body was introduced in Creo 7, GCRI will no longer work with any earlier versions.
Starting in Creo 7.0, GCRI is removed and no longer supported due to multibody functionality introduced in Creo 7.0
