Installing Office 2010 on XP SP3 fails with error that MSXML 6.10.1129.0 is required


  • Hi,

    I'm trying to install MS Office 2010.  I get the error that MSXML 6.10.1129.0 is required.  It looked like it had been installed but I removed what was there and am trying reinstall using KB933579 as described in Forums officeitproprevious thread 52967c75-353c-4f48-b872-1c3f1a152e6d.  When I first tried to install, it said that the installer "cannot update C:\WINDOWS\System32\msxml6r.dll because the file is protected by Windows.". I click OK and the install completes and Add/Remove Programs shows 6.10.1200.0 is installed.  I try to install Office again and get the same error that 6.10.1129.0 is required even though it seems a higher build of 6.1 is installed.  Since I thought the msxml6r.dll error might be the issue, I renamed msxml6.dll and msxml6r.dll in c:\windows\system32 and c:\windows\system32\dllcache and try the install of KB933579 again and I get a popup to insert my XP SP3 CD in the drive (with no option to point to anywhere else).  This is an older machine that I updated with Microsoft Update and don't have a CD for SP3.  I tried using the original OEM reinstallation CD (SP1a) and that wasn't acceptable.

    Can I do anything short of rebuilding the machine?
