Are you doing a network installation of Office 2007?
Create a new folder on the computer and then try copying all the contents from the Office 2007 disk to the new folder. Once done, open the folder > right click on the .exe file > click Properties > Compatibility tab > check the option ‘Run this program in compatibility mode’ > select Windows XP (sp3) from the drop-down > click Apply & OK. Now try installing Office from the setup file (.exe) and see if it helps.
