Now if that doesn’t work repeat the steps and try it changing the app code as well or you could even experiment with changing the number. It means with the version number in case if you are installing an apk of an already installed app.

This method should work just fine and the last method should only be used as the last resort if that APK file or app is really important for you and you desperately want to install it and also make sure that particular apk.
