The Wow6432 registry entry indicates that you're running a 64-bit version of Windows. The OS uses this key to present a separate view of HKEY_LOCAL_MACHINESOFTWARE for 32-bit applications that run on a 64-bit version of Windows. When a 32-bit application queries a value under the HKEY_LOCAL_MACHINESOFTWARE<company><product> subkey, the application reads from the HKEY_LOCAL_MACHINESOFTWAREWow6432Node<company> <product> subkey.
