Hi Glen

Thanks for the response - sorry I didn't make myself clear and is my fault. That Outlook key I have working already and was using it as an example to what I want. What I need is something that says

If KeyExist("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet\Settings\ProxyHttp1.1")
; exists - just exit
Exit 0
Else

*INSERT THIS KEY WITH VALUE OF 1* HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet\Settings\ProxyHttp1.1

EndIf

Is that bit I don't know - how to add that key in via the script if its missing with the value of 1 to be enabled.

Hope you can help!
