This is a very belated reply--I hope you moved on already. But, the answer
is you only have to do Detect & Repair for each SEPARATE office installation
CD you own. If all of your programs came together in one installation, then
just run it once in ANY of the programs included in the installation--Word,
Outlook, Excel, etc. BUT, if you purchased separate Office applications
beyond your original suite--you have to run Detect & Repair for each of these
additional applications--examples can include Publisher, FrontPage, Access,
etc. If you don't repair EVERY 2003 Office Application, the installation
will keep failing until you do. Good luck.
