hmmmm... I can at least download it without problems, and it's running like a dream on my otherwise buggy and grumpy computer (except for being a bit slow to show up). So I can't really see what might be the problem. It might be some antivirus programme or something similar that is messing with the installing. They generally don't like any kind of installations (at least not on my computer...).
And did you try to follow Rwilli's advices? (try downloading the 1.5.1.4 version again, and see if it works - you might have managed to install one of the buggy versions first, so that this is messing with the newest one).
It's just that if you post requests of getting rar files of the S2pack files every time you want to download sims - there will be a lot of work both for you and for others. Better sort out the trouble sooner than later
