There could be several reasons why you're unable to install apps, games, or updates on your Nokia Lumia 520. Firstly, ensure that your device has sufficient storage space available. Additionally, check your internet connection; a weak or unstable connection can hinder downloads. Lastly, verify that your device's software is up to date and that you're signed in to a Microsoft account with the correct regional settings, as some apps may not be available in all regions.
