I'm having the EXACT same problem that laurens34 describes below. I am
running Vista Home Premium and just installed Office 2007 Small Business. My
Outlook has 'magically' stopped launching the Windows installer but every
other office program IS still launching it. Also, I noticed in Control
Panel, Set Default Programs that the ONLY Office application that is showing
is Outlook. Word, Excel, Publisher, PowerPoint, etc. are not even listed as
being installed!! This is driving me bonkers and it's obviously a WIDESPREAD
issue as evidenced by a Google search although there don't seem to be any
sure-fire fixes for the problem. I've LOVED Vista up to this point but this
is ridiculous!!!

I have the same issue, and so are a lot of people (and will have a lot of
people)!!
I already tried everything, of course the installer clean up utility, even
going back to office 2003 pro but the problem persists. I think it has
something to do with user rights (i Ã*m an administrator and don't use the
UAC) in vista, things have to be changed in the register... Anyway, it's a
huge bug!! And very annoying.
Do you also get the error "stdole32.tlb" when opening excel?
Can you please let me know (anyone) if there is a solution to this issue?

Thanks in advance
