         with the Win32 file version limitations. This is required so that builds done locally, where '$(OfficialBuild)' == 'true',

    <!-- Split the build parts out from the BuildNumber which is given to us by MicroBuild in the format of yyyymmdd.nn
         where BuildNumberFiveDigitDateStamp is mmmdd (such as 60615) and BuildNumberBuildOfTheDay is nn (which represents the nth build
         started that day). So the first build of the day, 20160615.1, will produce something similar to BuildNumberFiveDigitDateStamp: 60615,
         BuildNumberBuildOfTheDayPadded: 01;and the 12th build of the day, 20160615.12, will produce BuildNumberFiveDigitDateStamp: 60615, BuildNumberBuildOfTheDay: 12

         Additionally, in order ensure the value fits in the 16-bit PE header fields, we will only take the last five digits of the BuildNumber, so
         in the case of 20160615, we will set BuildNumberFiveDigitDateStamp to 60615. Further, if this would result in a number like 71201 or 81201, we
         decrement the year and add 12 to the month to extend the time. -->
