If you see this under Wow6432Node the HKEY_LOCAL_MACHINE\SOFTWARE registry subkey, then is not an error.
The operating system uses this key to present a separate view of HKEY_LOCAL_MACHINE\SOFTWARE 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_MACHINE\SOFTWARE\ subkey, the application reads from the KEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ subkey. This entry indicates that you’re running a 64-bit version of Windows.
I used the Windows 8.1 version to test this information.
