"Symantec Endpoint Protection cannot be installed on this computer" error when installing SEP (Symantec Endpoint Protection) for Mac

An error was encountered while running the InstallationCheck tool for "Symantec Endpoint Protection."

Installer.log entries:

Package Authoring Warning: Symantec Endpoint Protection.pkg authorization level is NoAuthorization but was promoted to RootAuthorization for compatibility, ensure authorization level is sufficient to install.

Package Authoring Warning: Symantec Endpoint Protection.mpkg authorization level is NoAuthorization but was promoted to RootAuthorization for compatibility, ensure authorization level is sufficient to install.

Could not run InstallationCheck in the Symantec Endpoint Protection package. launch path not accessible

Installation checks failed.

 

Cause

The installation package may have been unzipped using a tool that does not preserve file permissions settings, or the package files otherwise do not have the correct permissions. This also may be caused by unzipping the package on another platform, then copying the .mpkg file to the Mac. 

Resolution

Unzip the install package using Mac OS X's Archive Utility or the ditto command in the Terminal after first copying the file to the target Macworkstation.

If the .zip file has already been decompressed using other tools, permissions can be restored to the package files in the Terminal with the following command:

chmod -R 755 /path/to/package/Symantec Endpoint Protection.mpkg

Once this is done, the installation can be attempted again.
