How to Fix App Not Installed | Invalid License Error?

When you try to install an app from the Google Play Store and get the error “App not installed. Invalid license,” it can be frustrating.

This is a common problem that can have a few different causes. Here are some tips on how to fix it.

Make sure you have an active internet connection

One of the most common reasons for this error is that your device doesn’t have an active internet connection. Make sure you are connected to the internet before trying to install an app.

Check your date and time settings

Another common reason for this error is that your date and time settings are incorrect. To fix this, go to Settings > Date & Time and make sure that the correct time zone is selected.

Ensure you are logged in with the right Google account

This error can also appear if you are not logged in with the same Google account that was used to purchase the app. To fix this, open up your phone’s Settings > Accounts & Sync and make sure that the correct Google account is listed at the top of the page. If it isn’t, touch Add Account, tap Google, then fill out your information for Gmail, etc. Once you have checked these three things, go back to Google Play Store on your device and try installing an app again. This should fix the issue within a few seconds. You can also check our video tutorial here on how to resolve this problem:

There are three different ways to fix this error. Here is a rundown of them:
