This is the registry key used to populate the NETFRAMEWORK40CLIENTINSTALLROOTDIR property. Can you verify that the registry key is set propertly on the XP box?
HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Client InstallPath Also in your verbose installation log you should see the property being set during the AppSearch action. Can you confirm? Also, you should have a PropertyRef for that property in your authoring (i.e. adjacent to your Component include this element: <PropertyRef Id="NETFRAMEWORK40CLIENTINSTALLROOTDIR" />) to ensure that the property will be setup in your MSI.

The problem on XP is that the registry entry for the eventmessagefile comes out as plain old "EventLogMessages.dll". It's supposed to tack on the .NET 4 path and be C:\Windows\Microsoft.NET\Framework\v4.0.30319\EventLogMessages.dll. On Win7 it does come out with the full path. This is causing the annoying message about a missing event messages. The rest of the WiX install looks to be working. I do have the WixNetFxExtension and WixUtilExtension on my setup project and the xmlns: set at the top. I did go back to my clean XP build and installed .NET 4. Is this a problem on XP or am I missing something?
