I needed a search engine to find your EULA. That can't be in your interest. If I was you I - had the installer copy an EULA.txt to programs dir - had the link to the online-EULA (http://adguard.com/en/eula.html) in programs 'about' and/or 'license' tab - had a link on the 'Puchase' page (https://adguard.com/en/license.html) --> This is a MUST!* - had a link on the homepage, at least in the bottom link section below 'License' * According to European law (EU) your EULA is invalid and not part of the contract because I had no reasonable way to get to know it before we agreed on the purchase. Actually you should have a checkbox on the 1st purchase page where buyers have to click "I have read and understood the license terms and I do agree." (find a better phrase for it ) to proceed.
