> As per the discussions on Windows installer moving forwards (https://wiki.shibboleth.net/confluence/display/~rdw@iay.org.uk/SPWiXDiscussionDesign) we need to make a small change to the VBScript to uninstall IIS.  For the record:
> - If for an Uninstall the registry value was empty at the start (prior to registry value deletion) then IIS was never installed and there is nothing to tear down.  [This is a change to the InstallScript - specifically the conditions to call the CustomAction]
> - Equally if it is not empty after registry value deletion then this is an upgrade (and IIS should be left intact) otherwise this is a final uninstall and IIS should be torn down. [This is to the VBScript]
