Verify ProActive Threat Protection via Registry or File

I need to verify ProActive Threat definitions on a few SEP 11 clients without console access or RDP access.  I have remote registry rights and access to the default shares as an admin.  Is the definitions date and revision stored anywhere in the registry or in a file in plain text?

I found this article for SEP 12:  https://www-secure.symantec.com/connect/forums/symantec-endpoint-protection-v121-proactive-threat-protection-definition-date

But can't find anything for SEP 11.  Any help would be appreciated.

Thanks,
