Wix Bootstrapper check for Net 4.5.2 & then downloads it also checking windows version - wix

Question

I'm trying to create a wix application that checks for windows install version and downloads the appropriate .net version. It should also check for the windows version.
I've created a .msi with a wix 3.0 project that checks for the appropriate windows version.
<InstallExecuteSequence>
<Custom Action="SetARPINSTALLLOCATION" After="InstallValidate"></Custom>
</InstallExecuteSequence>
<CustomAction Id="SetARPINSTALLLOCATION" Property="ARPINSTALLLOCATION" Value="[INSTALLDIR]" /> <Condition Message="Your version of Windows is too low">
<![CDATA[Installed OR (VersionNT <= 602)]]>
</Condition>
And I've create a burn bootstrapper that downloads .net 4.5.1 and downloads it if it's not installed.
<BootstrapperApplicationRef Id="WixStandardBootstrapperApplication.RtfLicense" />
<Chain>
<PackageGroupRef Id="NetFx451Web"/>
<MsiPackage Id="programName" SourceFile="$(var.SolutionDir)SetupProject1/bin/Release/programNameInstaller.msi"/>
</Chain>
I want to combine these two projects somehow, because apparently this doesn't function together for some reason. I'd like the windows version to be checked first if possible so that .net version doesn't download if the user isn't running windows that is high enough.

Okay I've gotten this figured out. Here is the finished version. (as of now) You will also need to install the dependencies for WixNetFxExtension.dll and WixBalExtension and I believe also WixUtilExtension
