Hi!

In PC with OPC Server for Siemens installed, OPC Explorer works well, Excel connects to the tags.

However, when i try an application to get the OPC Server interface I cannot get the IOPCServer COM interface.

I am using the ProgId "Matrikon.OPC.SiemensPLC.1" and querying for interface "39c13a4d-011e-11d0-9675-0020afd8adb3" , the standard OPC Server interface.

I got the message that the Class is not registered (REGDB_E_CLASSNOTREG).

Is there any dll that must be registered manually?

Any suggestions?
Thanks
