title: Is it possible to run an application compiled with VB4 on Windows 7 x64?
body: <p>I am converting a 16 Bit VB3 application to 32 Bit. Given that I have converted the Visual Basic 3 project into a Visual Basic 4 project, replaced VBX by OCX and compiled the application, should that result run on Windows 7 x64?</p>
  
  <p>I already know that </p>
  
  <ul>
  <li>32 bit applications can use Wow64 to run in principle</li>
  <li>I need to provide a bunch of DLLs and OCX</li>
  <li>I have to convert HLP to CHM</li>
  </ul>
  
  <p><strong>Are there any known incompatibilities of the Visual Basic 4 runtime (VBRUN) on Windows 7 x64? If so, is it sufficient to turn on some of the compatibility settings?</strong></p>
  
  <p>Note that this question is not about running the Visual Basic 4 IDE on Windows 7 x64. The development is done on a virtual machine.</p>
