MA is installed in an environment that has the Symantec Encryption installed.

The Symantec Encryption driver PGPLSP.dll is installed. This driver is optional during setup.

The Symantec PGPLSP.dll driver is trying to inject itself into the McAfee mcscript_inuse.exe process. The McAfee AAC protection driver blocks the attempt. The AAC protection block is designed to stop third-party dynamic library injections.
