installing on anexternal hard drive

danislilstar

So I had a computer that I used for gaming but then it crashed and so wile I still want to play sims I don't want to use up storage on my other computer. Now I am able to install the base game on my external hard drive but every time I try to install an expansion pack on my external hard drive it gives me an error message. Could someone please give me step by step instructions on how to do that?


Thanks
Dani
