I've just posted a topic about this on the forum: (gog.com/forum/amerzone_the_explorer_s_legacy/how_to_change_graphics_setting_this_game_does_not_run_properly_on_64bit_win_7) Movies freeze, basically rendering the game unplayable. Tried compatibility mode and other fix attempts, but to no avail. I think Gog.com should add a DosBox version to make it work in this OS or at least put an alert on the game page warning 64-bit Windows users not to buy it.
