How do I repair or change my NCM installation? (In Windows 2008 R2: I encounter Error 1721 when I attempt to repair my NCM installation. I encounter an error that "MDAC2.7 Sp1 cannot be installed on this machine" when I attempt to change my installation.)

Resolution:

Both errors are due to UAC in Windows 2008 R2 as related to how the Microsoft Installer handles NCM software components.

To repair or change NCM, uninstall NCM and then manually reinstall it, as follows:
