maintains for products that it installs, including the directories, files,
registry subkeys, and registry entries in which Windows Installer stores
configuration data. You can use Msizap to remove remnants of corrupted
Windows Installer installations that prevent you from installing a product
correctly.

MSIZAP requires the product code(s) of the installed program to work.
SharePoint has numerous product codes.  The product codes for the different
SharePoint builds can be found in the following location under the
ProductCodes registry key:

WSS v3 x32
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\WSS
WSS v3 x64
HKLM\Software\Wow6432Node\Microsoft\CurrentVersion\Uninstall\WSS

MSIZAP TW {90120000-1110-0000-0000-0000000FF1CE}

You will then need to restart the server.
