Anyone else having this issue? At first it failed because it "couldn't open the downloaded file" or something to that effect. I started it again and it just stops at 50%. I hit cancel and it's still "finishing" it's process. I hope this didn't mess up my install. Any advice is appreciated.
How long did you wait before trying to cancel the update?
Average time at our office for the After Effects CC 2014.2 is about 12-15 minutes, and it does tend to stall at certain percentages (usually 80% and 99%); this is due to a large number of files that are being copied and then cleaned up.
If the update is taking significantly longer on your computer, it's possible you may have a corrupt download or install. My recommendation would be to uninstall and reinstall After Effects, and then apply the updates again. Failing that, contact technical support.
Well, I let it go over the weekend and it was still at 50%. After clicking the cancel button, it's been going on that for an hour-and-a-half. There has to be some pref file that can be trashed before uninstalling the application. That sounds like Dell tech support in 1997. Just sayin'.
