Hi Experts,
AfterEffects CS5 fails to launch with a warning. I get a ‘Could not rename file’ warning with a file name path. The complete warning message I get from After Effects is shown in the below screenshot. But the strangest part is that such a file does not exist in my system. I attempted checking for this directory on the terminal too. And I failed to locate it. I have run permissions and restarted my system but still this message refuses to go away. What might be the reason for displaying this unrelated warning? Does anyone have any idea? Please share. Thanks in advance.

Could not rename warning received from AfterEffects
While working in AfterEffects CS5,  if it fails to rename a file then this might be a an issue with your workspaces file. These workspaces file are  preferences file that will be rebuilt to the default state if there isn't a file present. What you can do is try to delete the workspaces XML file from below:
Driver/users/username/library/ preferences/ Adobe/After Effects/12.0.  Hope this may help to  solve your problem.
Could not rename warning received from AfterEffects
This type of error happens as the Mac OS in your  machine  incorrectly allow permissions for some files and as result restricts Adobe After Effects to write or move the files that it needs to operate. This may be because instead of installing the new version freshly, when you try to upgrade your Mac OS, the OS often allow permissions of folders and files incorrectly. In order to solve this problem in Adobe After Effects, go to the preferences folder and type—
Users/Username/Library/Preferences/ Adobe/After Effects/12.0/ and all its contents as ‘writable’ and not read-only.
Another way is to delete the workspace XML files under —-
Drive/Users/Username/Library/ Preferences/Adobe/After Effects/12.0…. The workspaces file is a preferences file that will rebuilt to the default state if there isn't a file present. After doing this if there’s any option comes to install QuickTime then install QuickTime 7 which is an optional installation for Snow Leopard on Mac machine.
