File: D:\GameDate\Packages\Fullbuild1.package Error: Data error (cyclic redunbancy check) - How to solve??

I'm not sure if you still have the problem, but maybe this will help.

What I did when this happened to me is take out the CD when the error pops up, put it back in and press try again on the error box, another box should appear which states something about the CD not being found, you then pick your DVD drive and the installation should continue. The error may appear again a few times, you just continue to do the same thing.

If that doesn't work or you get fed up with it I'm pretty sure you can just press ignore each time and the installation should go on. Afterwards you open your CD's content (basically open the CD so you see what you have on it) Go to GameData, Shared, Packages and copy all three of the fullbuild files. Then you go ahead to the disc you installed sims to and find EA folder, where you simply look for the exact same folder as you did on your CD. Then you paste the files into it (if you have them then let them be replaced!) and the game should work. It worked for me 🙂

Good luck!
