That is because flash player is getting screwed over, and it has been explained all over the internet tens, if not hundreds of thousands of times already. Even in this topic it's already been explained as well.
You got a few choices on what to do:
1: Open Flash Player Control Panel and add the folder containing monmusu dinner as trusted location. You can now open the individual LemoNovel.swf files in the game folder with a flash player projector to see each scene individualy.
2: Find a browser, or a method to enable flash in your current browser (will eventually not be impossible most likely) then load the main html in said browser. May require step 1 to be done as well.
