title: Use 64 bits COM objects from 32 bits process
body: <p>I'm using the virtualbox api that uses COM on windows. If you have a 64 bit OS it will install the 64 bit version and the COM interfaces will be accessible to 64 bit clients but not to 32 bit ones. I'm told this is a COM limitation but I have seen <a href="http://www.gfi.com/blog/32bit-object-64bit-environment/" rel="nofollow noreferrer">ways</a> to use dll32 to "publish" 32 bit interfaces on the registry, so 64 bit processes can call these COM servers, but I can't find the inverse, accessing 64 bits interfaces from 32 bits processes.</p>
  
  <p>If I wasn't very clear I believe this person wants to achieve something similar: <a href="http://www.codeproject.com/Forums/1648/COM.aspx?fid=1648&amp;df=90&amp;mpp=25&amp;sort=Position&amp;select=1702805&amp;tid=1702805" rel="nofollow noreferrer">http://www.codeproject.com/Forums/1648/COM.aspx?fid=1648&amp;df=90&amp;mpp=25&amp;sort=Position&amp;select=1702805&amp;tid=1702805</a></p>
