Wix Burn, dependency installation failing

I have made a custom WPF UI in Burn to install my application, testing on my laptop its fine as it has .Net installed, but i have moved to a vanilla platform and have hit a snag right away. Burn tries to install .Net framework on the target, however, when i click "accept and install" a progress dialog pops up, then closes and is never heard of again. It hasnt installed anything, and the burn log is unhelpful.. i have posted it below. (i have removed anything "mespecific" from the logs, so anything in <...> has been removed. Does anyone have any ideas? bit confused why this is the case! is it something i need to do in the WPF code? (i.e. in the detection of packages?) Cheers - Chris

Ok, so i believe i figured it out.. There was an issue in how i had constructed the bundle xml. As the installer itself depends on the .Net, (as is mentioned on the internet in many places) this code snippet must be placed in a fragment..:

<!-- This defines the Installation packages that the main Burn ui depends on -->
<!-- think of this as the Installer prerequisites installer. -->
<PackageGroup Id="Netfx4Full">

  <ExePackage Id="Netfx4Full"
              InstallCondition="1"
              InstallCommand="/q /norestart"
              Cache="no"
              Compressed="yes"
              PerMachine="yes"
              Permanent="yes"
              Vital="yes" 
              DetectCondition="Netfx4FullVersion AND (NOT VersionNT64 OR Netfx4x54FullVersion)"
              SourceFile="$(var.PreReqsPath).NET\v4.0\dotNetFx40_Full_x86.exe" />

</PackageGroup>

This package relies upon these registry key searches:

<util:RegistrySearch Root="HKLM"
                     Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full"
                     Value="Version"
                     Variable="Netfx4FullVersion" />
<util:RegistrySearch Root="HKLM"
                     Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full"
                     Value="Version"
                     Variable="Netfx4x64FullVersion"
                     Win64="yes" />

These Wix Variables also need to be included:

<WixVariable Id="WixMbaPrereqLicenseUrl" Value="" />
<WixVariable Id="WixMbaPrereqPackageId" Value="Netfx4Full" />

Oh, final note, the package has to be referenced FIRST in the chain,

<Chain>
  <PackageGroupRef Id="Netfx4Full"/>

The main problem i had was not having an "InstallCondition" ASWELL AS a "DetectCondition", once these were both in, the install started functioning correctly.

It was a bit of a nuisance, as i was copying the examples i found online. Hopefully this fully tested (and working..) example will provide people in the future a solution to the same problem.

Thanks for the help in any case, frustrating that i struggle for three days with this then fix almost as soon as i posted to StackOverflow.. such is life! ;)
