Games will not download or update

download game without update if you complete download and install game, download update.

Sorry to hear it. Please try holding the power button on the console for 10 seconds until it shuts down to see if that helps.

The update, as all updates do, will install automatically when the game is loaded. If you recently downloaded the game the download already contains the update. The original download was approximately 3.2 GB, the current download is 3.88 GB.

You seem to be mixing up the terms installing and downloading, so I'm a little confused here.

If you're installing from disc, try disconnecting the console from your home network and try again to install it.

If, however, you are downloading you will of course need to be connected to the Internet for that to work...

If you are downloading, it sounds like it's possible your connection is a little on the slow side, in which case you just need to be patient and let it download fully. You should not be constantly cancelling and re-trying the downloads, or turning off and
on the console.

However, do try a complete power cycle before any of the steps above, to see if that helps you out at all.

Continue to hold the sync button until the Console has booted up completely.
