Welcome to Android Central! Are you saying that you're trying to install the actual WhatsApp app on your phone, or that you want to download a message on WhatsApp? It sounds like you're trying to install the app--where are you installing from? Are you unable to install it from Google Play Store? https://forums.androidcentral.com/e.../details?id=com.whatsapp&hl=en&token=7nbMAek0

If you're installing from another source, go to Settings>Security​, and make sure "Unknown Sources" is checked.
