.Windows7 64bit.
      xe is 32 bit application.
      Windows7(64bit) redirects 32bit appl's access to 64bit only directory to the other directory.
      eg. access to %windir%\system32 is redirected to %windir%\SysWOW64,
      So, xe shows dir-list of c:\windows\SysWOW64\drivers for c:\windows\system32\drivers.
