FIX WINDOWS PHONE APPLICATION INSTALLATION ERROR (EG TEAMVIEWER ERROR)

Generally if an app is compatible with your windows phone it should be able to install. If an error occurs, it is due to the following:

• You have an internet connection problem;
• Windows store is not available at the moment;
• You have not installed the latest available phone update (this usually occurs on win 10 phones);
• You installed the application in the wrong storage memory (some apps can only be installed in phone storage)

I'm going to explain the last one. If you install an application that is meant for phone memory into SD card memory, it will either refuse to download or it will download and not install. If the latter happens then it creates a problem, because no matter the number of times you install the application (even if you change storage location to phone memory) it will still detect the downloaded application and refuse to install. In this case the only solution is to either scan and fix memory card or you remove the memory card entirely from phone and then download and install app to phone memory before putting the SD card back.
