Issue Details

I have a PCI DAQ card that was running fine in my old Windows 7 computer. I have upgraded computers and moved the PCI card to my new Windows 10 computer, but I am getting error -50101 when I try and use it. How do I fix this?

Error -50101 occurred at an unidentified location
Possible reason(s):
The requested resources does not exist or exists but is in a state which prevents its reservation. The operation could not be completed as specified.



You may be putting the card in a slot that it is not compatible with,ensure that the slot you are trying to put your PCI card into is a PCI slot and not a PCIe slot. The card also may not be seating correctly.
Please try a different PCI slot on your computer and ensure the PCI card is seating correctly.

If this is unable to resolve the issue ensure you have the appropriate Version of DAQmx installed on your computer.
If you already have the appropriate version try force reinstalling DAQmx in order to fix any corruption..
