Installation is correctly finished, but I don’t know it works fine.

• Windows XP SP3 Professional
• Microsoft .NET Framework 4 Client Profile (Standalone Installer)
• Microsoft SQL Server 2005 Express Edition Service Pack 3

Apply these registry entries before installing “SQL Server 2005 Service Pack 3”.
