As I mentioned at #9, I keep Magix Connect. I guess that due to many complaints, Magix has just changed the way that Magix Connect is installed. Yesterday, this popped up on my screen.

When I ran it, it uninstalled the existing one and replaced it.

I think that this is what we'll see in the future, a request to install.
