Office 2007 seems to be installed, but it is not in Programs folder.

I tried installing office 2003 on a new windows 7 64bit pro computer.
After much hacking, Outlook would still not come up. There were many error messages, but the most significant was that the application version was not correct.

Turns out the computer came preinstalled with office 2007 activation assistant which seems to treat office 2007 as partially installed (even though it does not appear in the installed programs list).

I used system restore to return to the point before this mess started.  Now, what is the best way to completely remove office 2007 and start over? I found one web site that suggest i download trial verision of office 2007, install it, then uninstall, then uninstall the office activation assistant.  I that sound advice?

I got 2 solutions for that:

Number 1:
Download a trial version of the software at microsoft, install in your pc. Then proceed to remove Activation Assistant before you uninstall your trial version.

Number 2:
Use Revo Uninstaller (

Have you tried going in to your control panel open programs and features and then unistall from there?

Yeah, I tried that, but office 2007 is not listed.
there are two programs: 1) Office 2007 activation assistant,  and 2) office 2007 web components. which I uninstalled.   Unfortunately, things were already a mess by that time so I was not surprised that uninstalling them did not help.

to all experts:
So, my current plan is to
1) system restore a time before I did anything with office.
2) download trial version, install it and uninstall it.
3) uninstall any remaining programs that have office 2007 in their names probably the activation assistant and the web components)
4) reboot
5) check to see if the office 2007 short cuts are gone.  If they are still there, I will post again because it will mean that office still has remnants on my computer.
6) I will review the status of msmapi32.dll (My first post forgot to mention that my initial attempts for outlook would not start because it was getting a message that msmapi32.dll was corrupt.  I googled for that and found a page that told me to rename it. Afterwards google would start, but did not work properly. I will review the status of msmapi32)

Once all 2007 remnants are gone, I will try again to install office 2003 from CD.  I will post the results this evening

Got things to work.

I did a bunch of junk that I think was unnecessary then returned to original restore point again.  After the restore, the following sequence worked fine. I think all of these steps are required.

1) after installing Office 2003
2) uninstalled Business Contact Manager
3) uninstalled '2007 microsoft office system' (I did NOT uninstall sql server 2005 express.)   Be careful, it is at the TOP of the installed program list, which is why I didn't notice it sooner.
4) delete msmapi32.dll.  (Office later recreated it with a verision with mod date of 8/3/2003)

Other 2007 components like activation assistant are still installed, but things seem to work fine.  

For future researchers, I think any of the following error messages can probably be resolved in the same way.

msg 1) "cannot start microsoft office outlook.  msMapi32.dll is corrupt or the wrong version. This could have been caused by installing other messaging software. please reinstall outlook."
msg 2) "The ordinal 7375 could not be located in the dynamic link library mso.dll".
msg 3) "application version does not match"

Of course things may go wrong when I finish configuring pop3 etc, and running windows Update, but I think I am moving ahead now.

Yes, the uninstaller was the main tool needed, but the real secret was know WHAT to uninstall, and knowing to delete MSMAPI32.dll

Also had to uninstall microsoft office 2007 primary interop Assemblies.  It was causing windows update to fail.
