Major problem with Microsoft office 2007 pro

[satinpc]

I want to completely uninstall the software so i go to control panel-->add or
remove programs-->then i click remove Microsoft office professional 2007.
here is the problem, an error pops up telling that "setup cannot continue
because a required file is either corrupted or not available. run setup again
from the original source disc or download location". by the way this is a
trial version that is 498MB. Plz tell me wat to do. i got the trial from
microsoft website.
