 ### WOW64 support
 
  WOW64 (Windows 32-bit on Windows 64-bit) is a feature of 64-bit editions of Windows that enables 32-bit applications to run natively in 32-bit mode. Applications function in 32-bit mode, even though the underlying operating system is a 64-bit operating system. WOW64 is not supported for [!INCLUDE[ssCurrent](../../includes/ssnoversion-md.md)] installations. However, Management Tools are supported in WOW64.
