So I'm trying to automate some measurements using a NI VirtualBench and Teststand. I am having problems so I wrote a very simple sequence to open the DMM and then close the DMM and I fails. The initialize.vi returns a handle (_dmm0) but the close errors out with
VirtualBench.lvlib:DMM Close.vi:3060002
NI-VirtualBench: Invalid session.
I am sending the received handle from the initialize to the close using a FileGlobal. Any thought as to what might be going on? I also have older VirtualBench sequences that previously ran but are now also failing. The only thing I can think of is during the installation of other equipment drivers my environment is no longer compatible with the VirtualBench software.
