Is it possible deploy a Windows 7 Floating - Linked clone pool for 10 VDIs and licensing via KMS?

Hello all,

I would like build a floating - linked clone pool for 10 VDIs and lincense them using KMS.

I've read that KMS solution is valid when you deploy more than 25 VDIs but if my VDIs are rebuild some times at the day, Why KMS wouldn't work for me???

I've a KMS installed and i think that work properly but when i build my Windws 7 pool for each computer i always receive this error:

"View Composer agent initialization state error (16): Failed to activate license (waited 1275 seconds)"

If anyone can explain me what i should do for resolving it.

Thanks
