I disconnected from the internet as told, and disabled all anti virus/malware programs. Still the same problem. Then I tried to right click..run as..(my account, I only have one user account- which is set to the administrator) didnt work, then at the bottom of the run as menu tried to select administrator, but my user account password didnt work and leaving it blank didnt work. Then i tried it in safe mode, logged in as the administrator-wth no password, and still the same problem. "ERROR Cannot create C:\Windows\System 32\Drivers\ETC\hosts
