Just open the VI in LabVIEW 2020.  Are you having an issue opening it?

I can open the file just fine. When I click Run an Error -201003 occurs. It reads "Error -201003 occurred at DAQmx Create Channel (AO-Voltage-Basic).vi:187005"

The device I'm using is no longer supported by the current NI DAQmx. I had to download some old drivers, but I don't know if the old drivers are compatible with LabView 2020. Are they?

Do I need an older version of LabView since I'm using a CDAQ-9172 that requires NI-DAQmx 8.5?

Yes.  Read.

According to that, you can use up to DAQmx 17.5.


Then read NI-DAQmx and LabVIEW Compatibility

According to that, the newest version of LabVIEW that supports DAQmx 17.5 is LabVIEW 2017.
