   Compilation Note:
   You may see linking errors that look like these:
     <quote>LGHT0217 : Error executing ICE action 'ICExx' [...] The error code is 2738.</quote>
   The documentation for this error code talks about custom actions,
     even though the CustomAction keyword does not appear in this source.
   Certain WiX elements are implemented by MSI custom actions,
     which means this source implicitly declares some insofar as the Windows Installer sees it.
   These errors are benign and can be avoided by some fiddling with the registry on the development machine.
