"Error HRESULT E_FAIL has been returned from a call to a COM component" in VS 2013 (OPC client) RRS feed

  • Question

  • I get this error when im trying to add "items" to my OPC-server.

    I am currently trying to make our Visual Basic program to communicate with a WAGO PLC, with an CoDesys(OPC-server).

    We make connection with the server, but when we are trying to add an item we get the error message : "Error HRESULT E_FAIL has been returned from a call to a COM component". 

    The wierd thing is that we only got it to work on one of the computers at our university, the program was not programmed on that computer. For the OPC client we use "Graybox OPC DA Automation Wrapper" to get the communication with the OPC-server. 

    I think the problem is somewhere in the windows register, we have searched the whole web but still havent got a solution that fixes the problem. Does anybody know what the problem might be ?
