Installing a web application from an msi installer fails on Vista / Windows 7 / Windows Server 2008

Starting the installer results in a near immediate message reading: “the installer was interrupted before this application could be installed. You need to restart the installer to try again.” Additionaly, the eventlog shows eventid 11708 with a short error message stating “installation failed”

Resolution: You need to install the IIS6 Metabase compatibility component for the installation to work. The MSI installer requires the IIS6 metabase information to read the available websites and virtual directory’s on the server/workstation. The component can be added to IIS through the add/remove windows functions of the Software applet in the control panel.
