Every time I download it, I open the file and it requires me to use an app to use or open the game. but even then, the game doesn't even appear. It just shows me all the files that the game  consists of. I am new to pc, so I don't understand everything Any help would be appreciated. Maybe i could stream my screen to someone and they could walk me through it?

So basically this isn't an executable (an app basically) but a RAR archive (a folder in a file). If you use a tool like 7zip to extract it, you should get OH_MR_KRABS.exe, which is what you need to run
