This section contains all help you will need. First of all, you need an installed copy of Red Alert 2 (without extra-mods). It must be a working copy too.
You need an installed copy of WinZIP/WinRAR/7-Zip/Zip Genius. If you don't have any, go to the downloads section and download WinRAR.
Extract all the contents of the file to your Red Alert 2 installation folder (find this by going to the shortcut on your desktop, double-clicking it, then selecting properties. Go to Open File Location and extract the contents there).
3. Play the game!
