Hii sorry to disturb you'll but i tried downloading it this time from your site but the installer doesnt work again:(

The Sims 3: Pets - Installation Guide



1. Open the 'Sims3EP05Setup.exe' and follow on screen instructions.
2. When a serial code is needed, use one of the following serial codes:

YUKT-YRY3-CA7P-V03J-GFLT


This is a bit of the installation guide file. Please help me how i can use this file better.

Do you unzip it with Stuffit Expander? If not, you should download the program from the Mac app store (it's free) and use that to open the .rar

If afterwards you get an "integrity of installer cannot be verified" error, follow these instructions:
