Then launch Office.
Boot your Mac from the OS X installation disk, or the Restore disks, and do the same with the Disk Utility that you will find on the disk.
I have lost Excel and Word.
When I try to open Word, I get
"the application Word quite unexpectedly" Ignore/Report/Relaunch
and similarly with Excel (and the rest of Office; but it's only Word and Excel I really need.)
I don't know what I did to screw these up; both have been reliable for a long time.
I have restarted, trashed MSoft prefs, trashed MS folder, cleaned/maintained (Onyx), and even virus-checked (ClamXav).
I have tried to re-install from CD... new versions of the apps behave the same as old.
I have pulled out most of my remaining hair.
Can't afford to lose much more.
