However, they also write this: Q. I understand that Microsoft will not support MSDE on Windows Vista. But, will MSDE even install and run on Windows Vista? If yes, what functionality of MSDE will continue to run on Windows Vista and which one would not? A. Limited testing indicates that MSDE 2000 may install on Windows Vista, but this is not supported and Microsoft does not guarantee that it will install under all circumstances. Since the decision was made not to support SQL Server 2000 (including MSDE) on Vista, Microsoft did not conduct a thorough evaluation of MSDE functionality on Vista and is therefore not in a position to publish any authoritative guidance. Given that MSDE is an unsupported product on Windows Vista, we strongly encourage our customers not to run applications with the MSDE database on Windows Vista, even if they are able to successfully install.
