Always access the 64-bit registry key to read MachineGuid
When running a 32bit application on a 64bit Windows, the call to open
the key
"HKLM/Software/Microsoft/Cryptography/MachineGuid"
will by default be redirect to
"HKLM/Software/WOW6432Node/Microsoft/Cryptography/MachineGuid"
which does not exist.
Instead access the 64bit key from either a 32bit or 64bit application.
KEY_WOW64_64KEY has no effect on 32bit Windows.
