title: What's the difference between installing 32bit or 64bit apps on a 64bit Windows?
body: <p>So apparently, you can install both 32bit and 64bit compiled applications on a 64bit Windows system (Vista or 7). </p>
  
  <p>What's the reason why both versions are able to run on the 64bit OS? Is it good practice to install 64bit apps on 64bit OS? Any advantages/disadvantages to combining 32bit apps with a 64bit OS?</p>
  
  <p>Thanks!</p>
