    After Effects CC 2015 won't start on El Capitan - "Unexpected Failure on Application Startup"

    Filippos Protogeridis

      I recently purchased a Creative Cloud subscription and tried to Install After Effects CC 2015, but the application won't start. When trying to open, I get the following message:


      "After Effects can’t continue: unexpected failure during application startup"

      I have tried uninstalling and installing again, and also tried several older versions (CC 2014, CC) but still with no luck. The following shows as crash information in the Mac error log:

      26/11/15 11:12:30,598 After Effects[790]: *** Assertion failure in -[NSMenu itemAtIndex:], /Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1404.13/Menus.subproj/NSMenu.m:947


      My system information is the following:

      Is this a known problem and if so, is there any solution?


      Thank you in advance,
