Where can i find out the Patch/ Servicepacklevel from Backup Exec 2012

Hello , 

A good question , where i can find out what Patches an Servicepacks are installed in Backup Exec 2012 ? 

Pehaps i should know them in case of support or something . 

When i choose "Informations about Backup Exec" in the Program i only see the Build Number 

Thanks 

Michael
