Q295823 - MS Office Won't Install

[Geoff]

Hi All,

Knowledge base article Q295823 says that the
Windows Installer Cleanup Utility won't work
on Windows XP systems.

Does anyone know, please, how to remove
the old MS Office Windows Installer information
from the registry, as this is preventing the
installation of a later version of Office?

(I know how to use Regedit but I don't know
which registry keys need to be edited.)

TIA
Geoff

Hi, Geoff,

If you get the Windows Installer 2.0 SDK, you get MSIZAP2.0. This is what
you can run on WinXP machines AND other machines running Windows Installer
2.0.
It doesn't have a good UI, but a couple of folks have said it works great.

http://www.microsoft.com/msdownload/platformsdk/sdkupdate/

It's also available on your XP CD under

<drive>:\SUPPORT\TOOLS\support.cab

You'll need to extract it from the cab file. You can run msizap /? to get
the parameters for how it's used to remove Windows Installer data for
Office.

MsiZap needs to be run from DOS. Wherever you find MsiZap (the following is
from the Installer SDK), do the following:

C:\Program Files\Microsoft SDK\Bin>msizap t {Product ID}

Product ID mean the GUID. You might find it in a file in your TEMP
directory called something like "Office 2000 <edition>
Setup(####)_MsiExec.txt". If the TEMP directory is empty, you can find the
GUID using another method. Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
Click on the GUID folder numbers, and you should see a key called Display
Name. One of the folders will have MS Office as the display name, and the
folder number is your GUID. (You may also find it in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\10.0\Registration\ )

Make sure you use the curly brackets when executing
msizap t {GUID}
You'll know it works when you see a stream of text fly up the screen.
