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.
- 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
- Re-download the item from your purchase history.
This solution only helps in rare cases. If you have additional info on this, please let me know.
