It appears that you have your Windows Installer has mixed file versions.

I would recommend that you reinstall the latest version of the Windows
Installer. KB 324638 (see below) includes instructions as to how to install
v2.0 of the Windows Installer including a link from which you can download a
new copy.

MS KB 324638 - "OFFXP: "The MSIEXEC.EXE File Is Linked to a Missing Export
MSI.DLL:222" Error Message When You Try to Install, Update, or Remove a
Windows Installer-Based Program" (http://support.microsoft.com?kbid=324638).

Note that it is essential that you rename or delete all copies of msi.dll
before attempting to install the Windows Installer. The KB article explains
how to do this.
