Issue Details

I'm trying to get a LabVIEW 2017 project to operate in SignalExpress 2015. I have tried to save for a previous version to LabVIEW 2015 but when I do this, the DAQmx functions are visible with question marks. I cannot run the VI in LabVIEW 2015 because of this. How do I fix the DAQmx functions?


Reinstall DAQmx properly:

1. Type in search engine or for proper driver version
2. Install .exe and make sure to include ADE support
3. Reboot computer
4. Plug in deviceĀ
