We are using a PC to run Xpression Designer.
I am not seeing the same graphic card (we have a NVIDIA Quadro K600)
Under Device Manager>Ports, I have: Communications Port (COM1) and Intel(R) Active Management Technology - SOL (COM3). There is no USB Serial Port (COM3) listed.
I changed the registry entry for the serial mouse.
Once I set up the Datalinq according to the rest of the instructions, the value fields are empty.
