Took a few seconds on Google.... the version you are running is not "fully" compatible with Mountain Lion according to JAMF.

v9.96 Deprecated support for macOS v10.7 and v10.8 Features implemented in the Casper Suite v9.96 or later are no longer supported on computers with macOS v10.7 and v10.8. Workflows implemented prior to v9.96 will continue to function, but they may require earlier versions of the client applications.

Looks like 10.8 MAY work, but you're living on borrowed time. Past time to upgrade.
