Problem

I’ve downloaded something from the Sims 3 Store but I can’t install them. I get the following error message: Installation failed: Please make sure your game has the latest Software Updates and try again.

Cause

• This error seems to occur if the launcher can’t verify ownership of the item correctly.
• Check this thread: Exchange Content cannot be installed if you get this error on trying to install an exchange item

Solution

• Re-download the item from your purchase history.
