This will not appear unless you type (or paste) the whole thing in. If you have Minecraft installed, you should be able to find a file around there named:
There is a dot!
If you don't see that you either (somehow) specified other saving folder (unlikely) or some weird bug occured contact Minecraft support (https://help.mojang.com/).
If you see the .minecraft file but you can't play the game go to programs ("program files" on some devices) and try to search for Minecraft there.
I use Windows 10 it may not work on any other system (as far as my memory goes it worked on Windows 8 too).
You may also need to ensure you have enough available hard drive space to install this item or it will not install, quitting out automatically.
To check, look at the storage requirements on the store page. Then right-click on your My Computer icon, select properties and if "available space" is less than what Minecraft requires, you need to make space on the HDD before trying again.
