I have been asked many times before “Does SQL Server Dev edition can be installed on Vista operating system?”
I decided to find out the answer of this myself. I have just got new system which has Vista Ultimate Installed on it. I installed SQL Server 2005 dev edition on it. While installing it suggested that there are few component will not work with Vista and to make them work make sure to install SQL Server 2005 SP2. I was any way planning to install that. Once installation of SQL Server 2005 over, I installed SQL Server 2005 SP2. After restart I ran SQL Server 2005 and it just worked fine.
I am loving the combination of SQL Server 2005 and Vista Ultimate.
