Have a look at the File System Redirector article at http://msdn.microsoft.com/en-us/library/aa384187.aspx . In short, for 32-bit processes running under WOW64, %windir%\System32 is redirected to %windir%\SysWOW64, so "old" 32-bit processes continue to see a 32-bit environment. Starting with *Vista*, they added %windir%\Sysnative to point to the 64-bit %windir%\System32. There's more to it, e.g. %windir%\regedit.exe also being redirected, so make sure to read the article to avoid further surprises.
