Determine what version of software I have installed

In MAX, select System Information from the Help menu. Click on the System tab to display version information on currently installed National Instruments components including NI-VISA, NI-VXI, and T&M utilities.

You can also expand the Software category underneath My System in MAX and select a component to view its version in the right pane of MAX.

From VISAIC, select the About... option from the Help menu. This shows the version of NI-VISA that you are using, and also what version of the VISA specification it conforms to.

In addition, all of the 32-bit driver components have version resources. Under Windows Explorer, you can right-click any component and select the Properties option. This displays a property sheet with a Version tab. This tab has version information about the software and particular components.

You can also run the NI-VXI API utility program VIC and type ver at the prompt. The utility displays the versions of VIC and NI-VXI, and the latest board revision that this NI-VXI driver supports.
