If i purchase the C&C The Ultimate Collection from Origin store for my PC and install (Generals Zero Hour). after that can i use it for another PCs for my friends to playing the multiplayer game or each of them should purchase it too ?
@SimonLolo89 Origin purchases are personal anyway. As far as I know you can't log into your Origin account from two separate PCs at the same time, so yes, they'll need to buy it too.
As for playing online, you'll need to use the http://cnc-online.net/ servers.
Hello @SimonLolo89,
I believe this will answer your question http://answers.ea.com/t5/Origin/Can-two-people-play-on-the-same-Origin-account-at-the-same-time/td-p/488674

While Origin will allow you to download and install a game on as many computers as you want to, you can only be logged in on one of them at a time. If you try to log in on a second machine, you will be asked if you want to continue despite the fact that it will log you out elsewhere.
Edit: Oops Nyer beat me to it!
