CaptureCabTool is meant to take a cab file containing Kofax Capture exported Batch Classes and strip out the custom components. Kofax Capture will not let you import a cab file that references components you don't have installed. The workaround is fake-register the component so the system thinks they are installed, but that is very messy.
This was the first utility I made while working for Kofax, and also the last time I used VB6 to start a new project.
