Can't install Generations, Pets OR Town Life Stuff?

I've got all the other expansion packs downloaded and I've uncracked them with the ultimate fix. When I open any of the three installers, it tells me that it "Could not verify the integrity of the installer." Did I do something wrong? How do I fix it?

I used Stuffit Expander. I used it for the last few expansion packs I installed and there was no problem. I do remember having to make a disk image with the folder the last time... it's probably a good time to mention I'm using a mac?

It's alright, I figured it out! Thank you!

How did you figure it out?
Having the same issue

I created a disk image with each folder and installed from there.

Do I HAVE to install the other expansions? the #2 Install either The Sims 3: Town Life Stuff and/or The Sims 3: Generations and/or The Sims 3: Pets. *


does that mean I only have to install Sims 3 pets if that's all I want?
I have the original base game and only want pets.

I think you can just install Pets.

Thanks great, that worked! and yes bryan23, you can JUST install pets and it works.

Used the Right version of stuffit but the imstaller doesn't work and says Could not verify the integrity of the installer.

Open the program Disk Utility on your mac, then go File > New > Disk Image from Folder

Then navigate to your unzipped folder and let disk utility do its stuff. It might take a little while. Then open the .dmg file that disk utility just made from your folder and open the installer from there.

If that doesn't work I don't know what will
