Error: The Windows Installer service cannot update the system file C:\WINDOWS\system32\msxml6r.dll… while trying to install Microsoft SQL Server 2005 Express Edition

Question

Original title: Windows XP SP3 (spanish) Can not install MSXML 6.0 (english)

Hello,

Could you please help me solve the following issue:

I was installing Microsoft SQL Server 2005 Express Edition, and the message below appeared in the Summary related to the fail in the MSXML .dll.

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.

Is there any solution?

Thanks,

Petar

This is the workaround listed in the thread:

Set SFCDisable to 2 in the registry (http://support.microsoft.com/kb/222473 / "%SystemRoot%\System32\REG.exe" ADD "\%ComputerName%\HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v SFCDisable /t REG_DWORD /d 2 /f).

Hope this helps.

But, unfortunately, the passage of the twentieth user Umesh P on the forum does not work you need to install:

• Microsoft Core XML Services (6.0) - https://www.microsoft.com/en-us/download/details.aspx?id=3988
• SQL Server 2005 Express - https://www.microsoft.com/en-us/download/details.aspx?id=21844
• MSXML 6.0 SP2 - https://www.microsoft.com/en-us/download/details.aspx?id=9774

Also that :)
