I am trying to install SQL Server Express 2008 on my Windows XP Professional development machine. I get the error "SQL Server Express 2008 with Service Pack 1 is incompatilbe with product SQL Server 2005 Express Edition".
I have SQL Server 2005 installed on my machine but not the Express Edition. I may have had the 2005 Express Edition installed at one time but removed it to install the full 2005 Edition. It's been a while since I did that.
What steps do I take to get the 2008 Express Edition installed? We use SQL Server 2005 at my company and I still have to work with 2005 databases.
