2. Install Red Alert 3 Beta 2, available at http://thepiratebay.org/torrent/4330136/Red_Alert_3_Beta.
3. Install this patch.
If you don't install the patch yourself, the game will force you to download it using its own internal downloader before it lets you play.
This torrent is for those who would rather download the patch on their own terms, since the game's internal downloader doesn't resume broken downloads etc.
