From the OP via PM:
Yes I've looked in the download file. I have a HP Laptop Windows 10. I downloaded an app from the Google play store (at least I think I did) The thing is I can't find the stupid thing. Not only once did I download it, but twice. I couldn't find the app the first or the second time. Did I download it??? I read somewhere about a Windows Store, could that be the reason? Did I shopped at the wrong store?
