I downloaded the x64 version of the NOD32 v4 installer yesterday and have not been able to install it. Whenever I run the installer it runs fine until the progress bar reaches the "Compiling data files" part of the install. After perhaps 30 seconds or so, the installer initiates a roll-back and exits itself. I have deleted the ESET folder in Program Files and Program Data and restarted my PC but the same thing happens. v3 will install fine. I've looked in my Event Viewer and I can see some interesting errors occuring roundabout when I try to install NOD32 v4. The error codes are (in order of occurrence) 10006, 7000 and 7030. If anyone can tell me what is going wrong or what I can do to try and solve this problem I'd be very, very happy.
