Is there any issue (compatibility) between ZCM agent version 10.1.3 and Windows 7 Beta from 7000 to RC?

I can install the zcm agent 10.1.3 but it doesn't register. It doesn't appear in the zone.

When I click on the Register button, after a while, it states "Service Error. code: -21, message: Could not determine device type from <OS> tag: unsupported"

Is it supported or we'll have to wait another version of the agent?
