I was trying to update InDesign to the newest Version via the Updater to 7.5.3.
The Application Manager quit with the following Error:
Can anyone help me please.
Moving this discussion to the InDesign forum.
Have you tried running the update again, or downloading the manual updater, if using Help > Updates, or vice versa?
I started my Mac in Safe-Mode and repeated the updates and everything went fine.
Started in Normal Mode again and now can use the update.
