I just downloaded the sims and all the expansions. They are all seperate files but they are rips instead of images. I installed the sims and i can play it fine but when i try to install the expansions it says that that original isnt detected and that i need to reinstall from the cd. What should i do to be able to install the expansions, they are all .exe by the way. this has happened with all the games that i have that are rips. It installs but it doesnt do it through windows so its not on the program list and its not in the uninstall window or anything but it still plays fine. Any help is greatly appreciated.
