Now I got the app :)
After installing all updates on Windows update, I still did not see it. And after reading your answers, I tried to uninstall the update with the app, and reinstall it. But no luck. Still no app
I then remember reading something about drivers for the PC must also be up tp date, so I went to MSI (it is a MSI mobo), and downloaded a driverpack for this mobo. It turned out, that I had to update the driver for LAN. After this update and a reboot, the "app-flag" showed up in the taskbar, so maybe Windows own LAN-driver is too old? I did only two driverupdates, VGA and LAN. And one of these was the solution, it seems.
Thankyou for your time spend trying to narrow it down to a solution :)
