Hello, I can`t install ESET Smart Security Business Edition 220.127.116.11 (64bit). I did a clean Windows 7 Ultimate Edition 64bit install, did all Win Updates and the ess4 install does a rollback after driver istallation. Tried everything. There is no other security software installed, win firewall is deactivated, win defender is also deactivated. I have administrator rights, used eset uninstaller in safe mode but the same error occures every time. Any idea how to fix that?
