Greetings,

I'm having an issue and was wondering if anyone can help.

Background:
I had MS Office 2003 Professional installed on my computer. I then
installed MS Office 2007 Enterprise edition. at first, everything worked..
by that, all components: word, excel, outlook, powerpoint, etc.. Then i used
a registry cleaner to try and speed up the system.. didn't work out too well
and basically had to re-install MS Office 2007 enterprise edition. except
for outlook 2007. outlook 2003 is still installed and operates just fine.
BUT...

Issue: now when I try to install outlook 2007 from the DVD, it tells me
that it is unavailable. i can't select any of the other installation
options.. i.e. run from disk, etc.


Any ideas on what the problem might be? If I uninstall Outlook 2003 and
then try to install 2007, will I lose all the files/folders and/or .pst file?

many thanks....
