Problem with office 07

I have had office 07 installed on my computer for a few months now and never had a problem with it until now. Whenever I try to open the program it says, "The application has failed to start because the configuration is incorrect. Re-installing this software may fix the problem". I have tried to uninstall, but it says, "setup cannot continue because a required file is either corrupted or not available. Run setup again from the original source disc or download location." When I put in the cd and try to reinstall or uninstall I get the same error about a required file being corrupted or not available. Anyone have any ideas?

hmm...is the CD scratched?

***BUMP***

Also, in addition to the information above. I forgot to tell you that it is only excel that is not working. Word, Power Point, etc. works fine.

cd is not scratched

Any idea what the file is?

Can you try to re-install the program?

It sounds like you deleted the Office installlation files to save drive space, the installer cannot run sucessfully without all the required files. Have you tried Repair from Control Panel, probably end up with the same problem but it's worth a shot. You may have to manually un-install Office to fix this.

how do you do a manual uninstall?

are you running XP or Vista?
if XP go to control panel and add/remove programs for XP
click on office to remove and it should give the options to uninstall, repair or modify - choose repair
