Video Editing apps (After Effects, Premiere Pro, and Rush) aren't opening for me. My usual apps (InDesign, Illustrator, Bridge and Photoshop) open just fine. I've tried older versions of the apps, and the new versions. I click 'open' and nothing happens. Don't get an error code either.
Start by checking the event viewer logs. If the apps don't even make a blip when attempting to fire them up they eitehr crash right away e.g. due to a driver issue or there is a problem with loading components due to security stuff or a critical DLL being missing/ blocked.
