Looks like I figured it out. It is not really apparent to a newbie on WiX though so hopefully it saves someone else pain. In the BootstrapperCore.config you have:
<startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v2.0.50727" /> <supportedRuntime version="v4.0" /> </startup> Remove the v2 runtime line and the Bootstrapper will install v4 before moving on.
