Issue Details

My NI switch device is not recognized inside of LabVIEW. It does not automatically show up in the Resource Name drop-down and when I try to initialize my switch card by manually entering it's resource name, I receive the message: 

Error -1074118654 occurred at niSwitch Initialize With Topology.vi 

Possible reason(s): 
Invalid resource name. 


Why is this?

Solution

This behavior can be caused by antivirus programs interfering with the NI driver communication. Disabling your antivirus can fix this behavior. Additionally, if your antivirus software allows you to whitelist programs, you can whitelist the NI-ModInst DLL that handles the communication between the hardware driver and the resources. You can find these DLLs at C:\Program Files\IVI Foundation\IVI\Bin\niModInst.dll on a 32-bit system, or at C:\Program Files (x86)\IVI Foundation\IVI\Bin\niModInst.dll and C:\Program Files\IVI Foundation\IVI\Bin\niModInst_64.dll on a 64-bit system.
