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" 


The solution for this problem is to 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 configure on the block diagram.
