Office 2007 Installation Error in Windows XP

"Windows installer service can not update one or more protected windows files, installation failed" and the setup rolls back any changes. This happens because some dll are missing in your Windows XP.
1. Download fp4autl.dll and Fpencode.dll
2. Copy them to the "C:\Program Files\Common Files\Microsoft Shared\web server extensions\40\bin" directory.
3. Run the Office 2007 setup once again.
