Hi again,
Problem fixed by download and install of the latest version 8.6.1 of NI-DAQmx.
Also took opportunity to install VBAI 3.5.0.
All versions of VBAI now start OK.
Comments on VBAI 3.x for anyone who is interested:
Despite obvious excellent technical improvements since VBAI 2.6.1 some user aspects of VBAI 3.x don't impress.
As I have several inspections for operators to select between, the earlier 'Open inspection' dialog was excellent.
The new dialog is more generic, but not as simple or informative from a users perspective.
Also, I get the impression VBAI 3.x needs to keep all inspections in a single folder if navigation is to be avoided.
The separate folders of VBAI 2.6.1 combined with the simple 'Open inspection' dialog was much better.
Regards,
Greg Shearer
