Did the browser come packaged with other software on your computer? If so, your version of Google Chrome may be installed system-wide and you'll need to log in to a user account with administrative rights on your computer to uninstall the browser. Uninstalling a system-wide version of Google Chrome removes the browser for all user accounts on your computer.
