Backup Exec and SBS 2011

Hi

Previously i've installed MS SBS 2011 as a guest virtual server onto a MS Hyper-v box. I've installed Backup exec  (12.5 and above ) for MS SBS onto the host (since usually the guest cannot see the tape drive) and Backup exec has allowed this as part of the product licensing for Symantec Backup exec for Small Business Server.

I've just started an install for a similar setup but i wanted to put the backup software onto a dedeicated backup server (server 2008 r2) and only backup MS SBS 2011 )installed as a guest OS under Server 2012. However on completion of the install Backup exec 2012 seems to have gone into a 60 day trial mode. Is this scenario no longer supported does anybody know ?.
