title: Use 32bit "Program Files" directory in msbuild
body: <p>In 64 bit versions of windows, 32 bit software is installed in "c:\program files (x86)". This means you cannot use $(programfiles) to get the path to (32 bit) software. So I need a $(ProgramFiles32) to overcome this in my MSBuild project. I don't want to change the project depending on the os it is running on.</p>
  
  <p>I have a solution that I will post, but maybe there is a easier/better way.</p>
