A quick google for {"compatible; MSIE 7.0;" x64} suggests that IE 7 
running on 64-bit Windows does indeed identify itself as a 64 bit client

Similar searches throw up log entries from IE6 on 64-bit Windows:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; Win64; x64; SV1; .NET 
CLR 2.0 Win64; x64; ...

And from Firefox:
Mozilla/5.0 (Windows; U; Windows NT 5.2 x64; en-US; rv:1.9a1) 
Gecko/20060214 Firefox...

>From a quick perusal of tree.c, the part of the Analog source code that 
identifies the Windows version from the Browser string, you could 
probably modify it to identify Windows XP and Windows XP64 as 2 
different Operating systems:

 if (*c == '5') {
   if (*(c + 1) == '.' && (*(c + 2) == '0'))
     *name = "Windows:Windows 2000";
   else if (*(c + 1) == '.' && (*(c + 2) == '1')) {
      if (strstr(whole, "x64") != NULL)
        *name = "Windows:Windows XP64";
      else
         *name = "Windows:Windows XP";
   }
etc, etc. (I don't have time to test this at the moment).


I just saw your other post as I was about to send this - "MSIE 7.0; 
Windows NT 6.0; WOW64;" actually indicates that you're running the 32 
bit version of IE7 in the 64 bit version of Windows Vista. WOW is the 
Windows-on-Windows subsystem for running 32 bit applications on a 64 bit 
platform. I think that Vista64 includes a 32 bit version of IE so that 
32-bit ActiveX controls will work. There should be a link to launch the 
64 bit version somewhere in the Start menu.
