Office 2007 :The windows installer service cannot update one or more protected windows

I am trying to install Office 2007 onto a clean install of Windows XP (on a friends eee PC – it is really a sweet little laptop.. anyway), I get the error above about protected files. Here is the solution. (This may have happened because in optimizing XP down, some files were deleted).

1. From Windows install disk goto E:\I386 folder and open open (Double click) on the FP40EXT.CAB file. It should open.

(or – if you do not have the disk, find a working XP computer and go to C:\Program Files\Common Files\Microsoft Shared\web server extensions\40\bin).

2. find fp4autl.dll in the list and copy it (ctrl-c)

3. go to c:\program files\common files\microsoft shared\web server extensions\40\bin and paste it (ctrl-v)

4. Restart the 2007 office install

Viola! (thanks guys over at http://forums.techarena.in/showthread.php?t=627360)
