After posting this I tried once more and it somehow magically works.
My pc arrived with Ubuntu Linux. After using it for some time i decided to do fresh installation of Windows 10. Now I can't install My Dell app from Microsoft store. I have tried to edit registy but that did not work for me.  Here are all screenshots. Thanks in advance, Petar [IMAGE][IMAGE][IMAGE][IMAGE]
