HI,
Microsoft describes the error as: "This code means that the device failed to start (for example, it is missing or is not working properly). To resolve this error code, make sure the device is attached to the computer correctly. For example, make sure all cables are plugged in fully and that all adapter cards are plugged into their slots fully."
What GPIB hardware are you using?. What OS? Make sure you are using the lastest driver for your Hardware/OS combination. Check the drivers at
Gpib Driver updates.
Try installing the interface in another PC to determine if there is a hardware problem with the GPIB interface.
