title: Using x64 dll in x86 application
body: <p>I have a DLL that needs to operate large ammounts of memory and must be x64 to do that, but the application, which calls it is x86 and can not be converted to x64. COM is already used for interaction between application and the dll.</p>
  
  <p>Is it possible to use surrogate process for that purpose? </p>
  
  <p>I know that it is possible to do such a thing in the opposite case (run x86 COM library in x64 application), will there be any difference?</p>
