body: <p>i have a window 7 and i installed sql server 2005 and sql server 2008 together on my os

  <p>say SQL Server 2008 on top of SQL Server 2005 on the same machine may cause this problem, and if you remove SQL Server 2005, problem is solved.
  but i do not want remove sql server 2005, do you have any solution? </p>
