Sorry, but there is so much missing detail that even if I guessed it was Windows then we have XP, Vista, 7 and 8!
Did you try Chrome in another user's account?
I found the Chrome Browser quite convenient. But one day, (about 4 days ago), the Browser would not run.
I then uninstalled the Browser - reboot the computer - reinstalled the Browser. But still I cannot run the Browser again on this computer.
Can someone tell me what happened and how I can regain the Chrome Browser.
