So I went through all my files to double check how the hell I installed everything; and it was as simple as dropping all the additional folders into the "main SMA folder" that was extracted from its zip file (a few people already stated this)....
I included two very basic pictures...First picture shows the main zip file you should extract first (into a place you can remember), Second picture shows how everything should look after dropping all those zipped folders into the main one...Also the second picture highlights the application (.exe) that you run to start the game.
If this doesn't work for you, I suggest upgrading your windows video drivers or dedicated graphics card drivers (or PC)
