Not without a lot more information.
First thought would be to uninstall and reinstall.
Second thought would be to uninstall, use the Adobe CC Cleaner tool, and reinstall.
Other than that, maybe you could share with us some technical info like whether or not CC 2014, CC, or CS6 work on your machine.
Or, I dunno, knowing what OS and hardware you're using, might help...
CC 2014 worked before I upgraded. I'm reinstalling 2014 now, since it was removed during the upgrade.
I'm on a Mid 2011 iMac running 10.10.3
I've uninstalled AE2015 and reinstalled it, still gives the same error.
Luckily AE 2014 is working just fine for now.
I've now also tried the Adobe CC Cleaner tool and it doesn't work.
