Interesting on my Widows 7 machine there is nothing at
HKEY_LOCAL_MACHINE\SOFTWARE\SereneScren\MarineAqua rium3 (Typos noted) but instead find mine at
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SereneScre en\MarineAquarium3 but the RegCode just shows 0000 00 . The data between the 00 and "." is hidden.
