here's the problem,
I once played sims 2 before with my netbook and it really worked well, it has no lags, no problems really.
I've installed it on a external hard drive for me to play it automatically on another laptop that my father bought before.
When i try to open it in my father's laptop, it says an error that the base game was not installed or when i launch from the base game, it says that it needs to be reinstalled, but when I put back the external hard drive to my netbook, it runs ok.
Please help me solve this issue because I want to play sims 2 in my father's laptop because it has higher specs that my netbook.
Sims 2 Double Deluxe
and many other stuffs.....
