Sims 3 (Mac) Installation Error University Life

by Guest Sat 31 Jan 2015, 05:45

Hello,
I am a new user of this website. Recently I downloaded "The Sims 3 University Life" from this website's download page. I have the base game. In order to play the base game I need to download at least 1 EP so I selected Uni Life. Now, when I have everything and select the Uni Life Installer file a message pops up "The application 'The Sims 3 University Life Installer' can't be opened."

I also looked at the guide of Sims 3 Mac guide and followed everything, yet its the same error. Please tell me what should I do.
I have also uploaded the image of error pop up. If any idea please assist.

Thank You!
Regards,
