Issue Details

I'm using the NI-DMM/Switch Express VI in my LabVIEW application, when I try to open and configure the properties of it, I get the message "Unable to view properties" 


This issues has two possible solutions
  • Install a NI-DMM driver that is a lower version then 19.0, because NI-DMM 19.0 driver drops support for Express VIs in LabVIEW, existing code created with earlier versions of NI-DMM that contains Express VIs will continue to execute, but the Express VI cannot be reconfigured from a dialog box.
  • The additional solution, on how to reconfigure this Express VI is, to right-click the Express VI and select Open Front Panel»Convert. This will convert the Express VI to code, that you can edit on the block diagram.

Additional Information

Make sure the NI-DMM driver and LabVIEW versions are compatible, see table of compatibility and the NI-DMM download link in the related links bellow.
