How do I get my hands on ProClarity 6.3?
You can get 6.3 through the MSDN, MVLS, the fulfillment desk 1-800-248-0655, or via an evaluation copy at the public https://download.microsoft.com site. 6.2 hot fixes are no longer available since the product version is no longer supported. You must upgrade to 6.3 to receive support and updates.
