Issue Details

I've just installed and activated LabVIEW. Since I need to compare multiple VIs or merge multiple VIs, I tried to select Tools»Compare and Tools»Merge menu items from LabVIEW toolbar but these items are not available.

Why does this occur? Do I need to install additional software?


Merge VIs, Compare VIs and Compare VI Hierarchies tools are only available in LabVIEW Professional Development System. They are not available in LabVIEW Full or Base editions.
