title: Will win32 bit applications run on a 64 bit server?
body: <p>Here's my scenario: the company I work has applications deployed to a 32bit Windows 2003 server and they want to move to a Windows 2008 Server that is 64 bit.  It has been noted that these 32bit custom developed applications will not run on a 64 bit machine.  I was not aware of this.</p>
  
  <p>I have always thought that 32bit software CAN run on a 64 bit OS and just use the 32bit address.  A 64 bit software on the other cannot run on a 32 bit OS.  On a 64 bit, one does have to create 64 bit software but can and still also create software that is designed for 32 bit machines.</p>
  
  <p>Can someone please elaborate on this?</p>
