You need to install a torrent client, such as uTorrent or Vuze. If ThePirateBay is down, use How to download torrents (if you are not familiar) I found one torrent which automatically install all expansion packs, you are no longer needed to install expansions one by one and enter serial numbers: But The Sims game is split on multiple torrents due to having numerous expansion packs, which require entering serial numbers which may take a while to find them and install all expansion packs, whole job taking about 3 hours. You may have been aware of BitTorrent filesharing network, where you can download games for free. However, the Ultimate Collection, although contains the full game including all expansions and stuff packs, it do not contains expansion packs individually so they cannot be played with AnyGameStarter, used by me to create basegame-compatible content.

Some people uploaded Ultimate Collection on various file hosting services, where anyone can download for FREE: !tT5GkB5Y!8tEL-uoB7_aJG8Il9CREyQ

Only people who grabbed the free download at right time can re-download the game at any time. In 2014 EA Games offered The Sims 2 Ultimate Collection for free download via Origin for a limited time of one week.
