Installers are not my thing at all, but it sounds like that "Pserenescreen" file might be the result of the 64-bit version of Windows not having been completely installed, and creating some kind of conflict with our earlier installer. Did you download a recent version of Marine Aquarium, or are you installing using an older version? Are you doing an Uninstall, or just deleting files?
