Hi I can't find \etc\hosts in the C:\WINDOWS\system32\drivers\ and AGV keeps telling me it has a reading error in this line. All the forums I have been to tell me to open the C:\WINDOWS\system32\drivers\etc\hosts folder and edit it to... but it isn't there how do I reinstall this folder(\etc\host) and is it needed or am I justing worrying for nothing.

The C:\WINDOWS\system32\drivers\etc folder usually contains a few files that specify some network mappings. Not sure how your went missing though..?

Just create the etc folder and a host file yourself. The HOSTS file is just a text file, and by default only contains one line of actual code:

127.0.0.1 localhost

Hopefully that's all you need to rid yourself of the error.
