if you read the forum rules you would know that Afterdawn does not condone the use of pirated games. you wont get any help asking that type of question around here
There could possibly be a fix or something, but I doubt it. Bad rips of games result in this type of error, but I don't think the game would have been counted as properly installed if it did not install everything. The parts that are possibly corrupted or not there are unlikely to be fixed and you are best to get the game a different way or trying again. I hope you tried at least reinstalling the game?
I have the same problem... I can't install the expansions either.... does anyone know how to make build mode work.... and also i can't install the expansion university. it ays to put in the sims2 disc 4 i do and nothing happens...
