Howto add Rockwell Software OPC Automation Reference

Hello everyone

I would like to add the Rockwell Software OPC Automation Namespace into my VB Express 2010 project, but i could find it.

Anybody here who can tell me how to do this? I have searched under Project - references, but there are only Microsoft, System and Windows namespaces listed. The RsiOPCAuto is not there.

I have a Win7/32Bit OP and RSLinx 2.59 if this information is helpful for you.

Those automation wrapper is usually not added the project reference view upon install. It should be located on the local PC and you will need to browse for it and add it manually.
