Hello, I hope this works, and in this page
http://support.microsoft.com/default.aspx/kb/923718/en-us it says no to
install the cleanup utility because it corrupts other installers
1) Uninstall all existing Office 2007 suites and/or standalone apps via the
Control Panel, if possible.
2) Go to Start/Run and type "installer" (w/o quotes). This will bring up the
Windows Installer directory.
Change to "Details" view if you are not in that view. If you don't have
"Subject" as a header, then right click on the headers in the directory,
click more, then choose "Subject" so you can see the Subject information for
each item in that directory.
3) Sort by Subject and observe any items that contain Microsoft Office 2007.
For each Office 2007 item listed, right click on the msi and choose Uninstall.
4) Check Services and stop the Office Source Engine service if it is running
5) Delete the following registry keys if present (the asterisk is a wildcard
representing any string of one or more characters):
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Delivery\SourceEngine\Downloads\*0FF1CE}-*
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*0FF1CE*
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ose
HKEY_CLASSES_ROOT\Installer\Features\*F01FEC
HKEY_CLASSES_ROOT\Installer\Products\*F01FEC
HKEY_CLASSES_ROOT\Installer\UpgradeCodes\*F01FEC
HKEY_CLASSES_ROOT\Installer\Win32Assemblies\*Office12*
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\*F01FEC
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\*F01FEC
6) Find and delete all keys under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
with a valuename of UninstallString that contains a value with
*\Office Setup Controller\setup.exe*
7) Delete the following folders (if present):
%CommonProgramFiles%\Microsoft Shared\OFFICE12
%CommonProgramFiles%\Microsoft Shared\Source Engine
%ProgramFiles%\Microsoft Office\Office12 (this is the default location
but can be changed during the installation)
%appdata%\Microsoft\Document Building Blocks
%appdata%\Microsoft\Templates
On all drives remove all folders below the MSOCache\All Users folders
containing the string *0FF1CE}-*
8) Clear the content of your temporary files directory (go to Start/Run and
type %temp%)
9) Reboot
10) Temporarily disable antivirus software and related services
Once you've completed these steps, you should be able to successfully
reinstall Office 2007 and the B2TR update.
IMPORTANT NOTE: Prior to installing the B2TR update(s), you should first
install all desired Off2007 applications, or a 2711 error will occur. This is
documented in the 2007 Microsoft Office System Beta Known Issues/ReadMe at
http://officebeta.iponet.net/en-us/products/FX101517941033.aspx (see the
"Setup (client)" section).
