LabVIEW crashes when trying to use VISA controls

[NJW]

When I try and place VISA controls onto the front panel or a constant into the block diagram LabVIEW crashes and says that LabVIEW.exe caused an error and that LabVIEW must be restarted. Is there some setup required in order to use VISA or is there something wrong with LabVIEW?

I saw something that sounded exactly like this myself on two PC that where running some kind of "Eveidence Eleminator" software that got its hooks into everything.

I never did get it running on those two machines.

I saw something similar when trying to access a serial port that was hanging off of a USB gizmo.

We downloaded the latest and greatest version of the driver for the USB to serail device
and
upadted NI-VISA to the latest and greatest.

Then everything worked.

It was just like you mentioned, LV looks fine right up until you drop a VISA control.
