Our Altera License Daemon has stopped working.

· I ran the Sysinternals Process Monitor tool, attempted startup of the "Altera License Manager" service, then stopped the Process Monitor data capture as soon as the service startup failed.

· I examined permissions on C:\Altera and C:\Altera\Log_File. They were completely typical: "CREATOR OWNER" had full control and "SYSTEM" had full control.

· After that, the service started without problems
