Ditto! I use Outlook 2010 but the same issue with me. I suspect the problem is that Windows 7 (I upgraded - not clean installed) does not permit this app to run. I've tried it in Safe Mode as well but , even though I get the old interface offering the option to set the backup location and to save the backup, when I exit Outlook, nothing happens (whereas before I got a save progress screen window). What a pity as this WAS such a neat app that saved a lot of hesartache over the years. I wonder if anyone has worked out a tweak yet to resolve this problem!
