For my part the process never exceeds 2 of 37, is this normal?
As I've said in the previous post, if it has updated everything, there's nothing else left to do other than quitting so...it quits.
The updater is not "just" for GSX, is for all FSDT products, for all simulators so, unless you have *all* of them installed at the same time, you'll never see all steps performed, only the installed products are updated.
