During the installation of SQL Server 2005 (express edition) on Windows XP SP3, I receive the following error message. What can I do to fix this problem?

“The Windows Installer service cannot update the system file C:\WINDOWS\system32\msxml6r.dll because the file is protected by Windows. You may need to update your operating system for this program to work correctly.”


When you install an English version of SQL Server 2005 (or SQL Server 2008) on a localized version of Windows XP with Service Pack 3 which is not English version, you will get this error message. Just click OK button the setup wizard resumes and the setup will succeed. For further reference
