VAVA 4k Can't install update

Trying to upgrade the VAVA 4k from v1.25 to v1.42. It downloads the update just fine and then… it just sits there. The status bar says the whole thing was downloaded… ut thats it. No install or restart. Nothing. I can go back and it brings me to the system update page which allows me to “Download & Install”, but then it just downloads the whole thing over again, and repeat…?

Try reset to defaults then upgrade.
