I really thank everyone who would help me in this problem I have found. I have an old application in CLI/C++ compiled with Visual Studio 2008 on Windows XP and uses the Solid Edge 20's SEpartX.ocx. If I try to execute the program on Windows 7, the ocx doesnt show up and if I try to debug it, I receive an unhandled exception, in particular 'System.AccessViolationException' in mscorlib.dll.
Do I miss any frameworks or something similar?
Thanks a lot
Your issue may be due to the fact that V20 was not supported on Windows 7. You also may try asking this question in the Solid Edge Developer Forum as it is frequented by those that use the API.
