OPC server registration fails

Question

When trying to register the IGSS OPC server from the server configuration tool you get the error that opcproxy.dll cannnot be found. 

Answer

This problem occurs because the OPC Core Components are not installed on your PC.

You can either download and install the Core Components from the OPC foundations homepage or install the Softing OPC Demo Client here or Demo Server which you can download here .

The Demo client also provides an excellent tool for testing the IGSS OPC server.
