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

I fum­bled with this prob­lem for quite some time with­out much suc­cess after rein­stalling Win­dows XP on my eee PC. Then I found the solu­tion at Ben Shoemate’s arti­cle. I’m directly quot­ing his con­tents here:

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
