title: wix PersonalFolder issue
body: <p>I am new to wix (Windows Installer XML) so I folloed some tutorials like <a href="http://wix.tramontana.co.hu/tutorial/getting-started" rel="nofollow">this one</a> 
  but what I need is that the application will be installed in the user personal folder so I replaced ProgramFilesFolder by PersonalFolder in the code. but Ive got this error:</p>
  
  <pre><code>Error   1   ICE38: Component MainExecutable installs to user profile. It must use a registry key under HKCU as its KeyPath, not a file. C:\Proxym-IT\Projets Visual Studio\SetupProject2\SetupProject2\Product.wxs  18  1   SetupProject2
