Cannot Installing office 2007 error 1933

[ValentineSS]

Two days ago I formatted my system, reinstalled Windows XP and all other required softwares. While trying to install Office 2007, every time setup fails with the following error code:

Error 1933. The windows installer service cannot update one or more protected windows files.

As mentioned in the error about file protection, I tried removing the windows file protection but that too fails. No idea how can I fix it. Any advice please ?

Before formatting the system were you using any Trail office versions ? though chances are very less but I guess there would be some files left from the earlier installation. You should remove them first using Disk Cleanup and try re-installing Office 2007 again.

Alternatively what you can do is copy Fp4autl.dll from office CD and paste it to "C :\Program Files\Common Files\Microsoft Shared\Web Server Extensions\40\Bin\". now start installation and see if it works.

Even I am having the same problem and yet unable to fix it. It is my Office Enterprises, installed on 3 different computers and all working fine except mine. It is just unable to get installed on this pc and ends with the error mentioned above by ValentineSS.

Somewhere I read that Microsoft provides free phone support for Office Enterprises users. I will try to talk them tonight. Lets see what they suggest.
