Empower program for ISVs
I'm occasionally asked by ISVs about how they can establish a partnership with Microsoft. We offer Microsoft Empower for ISVs to meet this need. While it's not free, it is a good value, offering:
Up to five internal-use software licenses:
One (1) software license and up to five (5) Client Access Licenses (CALs) for:
Development and testing license: One (1) MSDN Premium Subscription Media Kit and five (5) user licenses**
ISV Advisory Service (10 hours)
