Adding MimeMap via WIX failed

I've been given a bug to fix an installer issue. Unfortunately, I know nothing about WIX, so I am not exactly where to start.

The WXS file is adding the necessary MimeMap, but when QA installed our app on Windows 2003 with IIS6, the MIME type was not set.

I am not sure where to start. We are using Wix 3.0. Here is the XML:

<iis:WebSite Id="DefaultWebSite" Description="Default Web Site">
  <iis:WebAddress Id="AllUnassigned" Port="80" />
  <iis:MimeMap Id="registerXapMimeType" Extension=".xap" Type="applic开发者_开发技巧ation/x-silverlight-app"/>
</iis:WebSite>

Any idea to why this MIME type was not mapped?

I'm doing almost the same thing and it's working; the only difference I can see is I'm setting it under the WebVirtualDir instead of WebSite element:

<Component Id="IIS6VirtualDirComponent" KeyPath="yes" Guid="blah">
  <iis:WebVirtualDir Id="IIS6VirtualDir" Directory="INSTALLLOCATION" Alias="[TARGETVDIR]" WebSite="IIS6WebSite" DirProperties="IIS6WebDirProperties">
    <iis:WebApplication Id="IIS6WebApplication" Name="[TARGETVDIR]" WebAppPool="IIS6WebAppPool">
    ...
    </iis:WebApplication>
    <iis:MimeMap Id="IIS6MimeMapXAP" Extension=".xap" Type="application/x-silverlight-app" />
  </iis:WebVirtualDir>
</Component>

same problem here, trying a custom action. I also tried putting the inside the node but that didn't work either.

for more details: Is there a way to get ALL the MIME types instead of wrinting a huge case statement?

Brian, I fixed this by moving the MimeMap registration to the WebVirtualDir as suggested by Si. Go figure...
