Cant tell if that was helpful or rude?
I didn't consider it could be viewed as rude, it's a very simple answer!
The portable version of the game doesn't require to be installed, that's all it is. It's the same game as the install version.
edit: Ah! Or did you mean because you asked about a mobile version before? Sorry If I gave you false hopes, I just figured it was a better name than "archive", which is what I called it before.
