While installing one of the AdobeCreative Suite 4 suites or point products on Mac OS X, the error "Unable to delete directory '/Library/Application Support/Adobe/TypeSupport'" appears in the installer log.
The current user and/or admin group does not have write permissions for the "TypeSupport" folder or one or more of it's contents. Or, one of the files contained in the folder may be in use by an active process.
Start by ensuring that all Adobe applications and processes are shut down. Next, disable any antivirus software, file indexing utilities such as Spotlight, and any other applications that scan files on your disk.
If you lack administrator access privileges, then Adobe Creative Suite may be unable to access necessary files. To determine if limited privileges cause the problem, log in as a user with access privileges, and try to recreate the problem. If the problem doesn't recur, then the account you were previously using lacks access privileges. Contact your system administrator to grant you access privileges.
See "Log in as a user with administrator privileges (Mac OS X)" (TechNote kb404926) for details.
Occasionally, a user account can become corrupted and prevent the installer from accessing or creating the necessary files and folders. Create a new account, log in to the new account, and then try to install or run the Adobe application.
