I apologize but I am not clear about your question.
EEM itself is Endpoint encryption manager and it can't be managed from the ePO server.
Please reproduce your query.
EEM is a seperate point product and can't be managed from the ePO server.
Regarding checking the version, please open EEM console (start=All Programs=>McAfee EEM=>EEM), log in to EEM.
In the EEM console=> Help=>About McAfee EEM.
EEM is seperate product. I am not sure, how it's installed under ePO directory. By default, it will be under \Program files\McAfee\EEM.
