I've got a similar issue:
When I launch the Creative Cloud Application, I get notifications to update the applications that have updates available. I've updated all the applications without a problem ... EXCEPT Premiere Pro.
When trying to update Premiere Pro, I get a reponse of:
"Update Failed. Unable to extract the downloaded files. Press Retry to download again. (U441l210)"
I've tried Retry multiple times with no success. Restarted the computer, ShutDown the computer; still no success.
I submitted a bug report to Adobe via their website bug report form.
Anybody else having this problem? If so, any success in resolving this issue?
My Computer -
MBP-RD 15" (1st gen)
I am having the same identical problem, but only on my desktop, laptop updated successfully.
I got it fixed.
Go to this page ...
... and follow the instructions and it SHOULD resolve this issue. At least it did for me.
Hope this helps and works for you all.
