Yeh, it's not a speedy process. It can take a minute or two, and there's no progress bar to let you know it's working. Maybe someday I'll fancy it up a bit. Probably not much I can do to speed it up, though; it has to open each DLL and get its version number. But the real slowdown is Excel, which is a dog to automate.
EDIT: I added a progress bar to avoid that kind of confusion.
