OK, I had the same problem. I suck at computers too.:original:
Here is how I do it, and it is super easy. Click to download it, then when it asks to open or save it, chose open. Then a folder will come up, and there will be an option saying extract all files. Extract it. Then the folder will come up again. Click on it a few times, until it comes up as (example) red footed tortoise; 931 KB. Ok, Minimize that. Then click on start, my computer, HP_Pavillion, Program Files, Microsoft games, then Zoo tycoon 2. Now open the window that you minimized earlier. Click and drag that icon with the animal name and number of KB into the window that you just opened. Then it should work. Thats what I do, and it always works.
