My understanding is that starting PI Server V. 3.4 OSI has implemented GUID feature. Due to this added feature, client applicaiton must now set GUID otherwise the connection will be denied.
This issue I have is that my application(in house) is not modiefied yet to set GUID but able to get connection and pull data from the PI server(V 3.4375.80) without setting GUID. Due to this I can not test changes I will make to my application to implement GUID accurately.
Please note that THTE license file for my PI sever was created using vCampus.
Your help regarding this matter is highly appreciated.
