OPC Data Fix
The OPC Data Fix is an easy solution to connect to OPC Servers that do not run as a Windows Service and require a Desktop Account permission to connect to the OPC Server. First verify with the OPC Foundation Sample Client if the OPC Server is working properly with Desktop account permission.

Start the OAS Service control manager under the program group Open Automation Software.
Step 2
Select the Enable OPC Data Fix button.
