Hello, thank You for your recommendations, but their are unable resolve the problem. I switch off windows defender (windows 10 v1803) and brandmower -no result! I have not any antivirus yet. I started up Instaleer/updater like administrator -the same! I tried to update/install on different computer separately X10/X11-no result!! the best way- I suppose- connect to me via TeamView- and check the problem
