For test purposes you can have different ECTR releases installed in parallel on one machine.
Please make sure, that you have registered (regsvr32) the latest version of \basis\sys\win\lib64\plm_conn.dll
For the individual CAD system there is a different behavior:
- Creo uses a JAR-library directly from the applications directory of the started ECTR version. No registration required.
- NX uses the registered Plugin-DLL. If you do not want to use the registered DLL you can turn that off with UGII_D_PLMCONN_REGISTERED = false in \applications\ugs\customize\config\default.txt
- For CATIA V5, Solidworks and SolidEdge the correct DLL needs to be registered (regsvr32).
- For Inventor and AutoCAD the loaded DLL is stored in a specific path, which can also be overwritten by a start-up script.
regsvr32 requires admin rights on the client.
