FileForums - Red Alert 2 Help

Hi all, i am new here so i don't know much. Anyway here goes. I downloaded the full version of of Red Alert 2 from a program called "Bit Comet". It took me a few days to download. So i extract it with "Win ISO" and put it in a folder. Next i opened the folder and there are two other folders there called "allied" and "soviet". I have two questions. 1. Does it matter from which folder you install fisrt? 2. When i open allied or soviet and click on SETUP an error message says that there is no disc in drive please try again; is there a crack so i can install without disc? (because there is none obviously)
