This is a manual host file editor , but you will only need to open it to Make hosts read only on your file, it can make you a backup too while you at it
Click that button at the top right and re-run your installer to complete the job.
(you can lock it again if you choose by running Hoster again.)
Oh and grab a beer now all the hard work is done
