If you get an error like in the screenshot above please uninstall the browser then re-install it and it will 100% be up to date.

You can always download the latest version of Google Chrome here - https://www.google.com/intl/en_uk/chrome/

You must do this in the order I have given you for it to work properly!

1) Uninstall Chrome

2) Uninstall gameroom

3) Reinstall chrome so it will be the newest update

4) Re-install Facebook gameroom

This will help you as it won't ask you to update chrome, since you will have already installed the newest version before you re-installed Facebook gameroom. But for it to work correctly you MUST do it in the order that is given to you.
