Thanks for the clarification. I thought the portable was the same as Windows Store, regarding folders, as I read on another forum topic, and presumed the same problem. Neither did I realize about the copy-over patches existance.
But I forgot to mention, and I don't know if it's the same for both, but it's about going from an old normal install version to a new Windows Store version. Sorry, I use to live in my own mind too much, often forgetting to point out important parts of what I want to say.
