Uninstalling Exchange Fails

I saw this issue many times on computers running Windows XP where the Exchange 2007 management tools are installed. For some reason the Exchange management tools need to be removed or reinstalled, but when the installation wizzard starts all options are grayed out. In which you cannot deselect the Exchange Management tools. Even when you start the installer you get the message the the install cannot be performed.

The easiest way and rather fail-safe is to remove the MSIinstallation through MSIEXEC.

Op a commandprompt and type following command:
Exchange 2007
[Code]
msiexec /X {24B2C164-DE66-44FE-B468-A46D9D5E6B31}
[/Code]
Exchange 2003
[Code]
msiexec /x {73404-665-00000016-05064}
[/Code]
