Thank you for your replay and time 1PW, 5. Today I've tried for a few times to chat with them from the link you provided, but: "No support representative is available to handle your session at this time. We apologize for the inconvenience. Monday-Friday, 5 a.m. – 7 p.m. PDT" I've tried to call a few centers from ESET :: Select your country different countries but no answer anywhere. Yesterday afternoon(Friday 01.01.16) I sent e-mails, and fill in web sites contact forms on some official ESET Countries with the questions, but not replay yet. Even on some ESET web sites on the Contact page was written that the technical support is 24/7 available, but now, after 24 hours, no answer yet. Probably my questions are not a priority for the technical support, or is not their duty at all to help me, and maybe ESET sales departments are responsible to answer to my query, and hopefully they will be available only on Monday. Add for question 1, from the initial first post. I've done my best(in my available time for it) to find it in here: Software End User License Agreement | ESET but I couldn't resolve it. Regards.
