I can select multiple apps, but it only updates the first. Then I must re-scan and select the next app.
Feature or bug? I see the list of missing updates in the right panel. I must BROWSE the panel on the left to select the desired patches. I think I should be able to select the desired patches in the right panel.
Can you try to delete the HKLM\SOftware\Patch My PC key and see if that helps?
