I had been running NOD32 for most of it's trial period and because I was very impressed, I ordered and downloaded ESS. The installer file is ess_nt32_enu.msi. I'm running a completely (as of 4/15/2009) patched/updated Windows 2000 machine that is part of a small home network. The installation of ESS proceeds as it should until the screen that asks me to choose what I would like to do with potentialy unwanted programs. At that point, the "Next" button is greyed out and no choices are displayed when trying to activate the pulldown. I can't go any further. I've tried this repeatedly with files downloaded at different times. The deinstallation of NOD32 apparently went fine. I've seached the registry for traces of NOD32 and ESS and removed the few keys I found. I ran the Windows installer cleanup utility and it showed no traces of any ESET stuff. I ran Sysinspector and it showed no traces of anything except Sysinspector itself. I had, before the installation of NOD32 about a month ago used McAfee. I removed their stuff and used the cleanup program to remove residue. I've contacted ESET via their support website. They have not responded. Anyone have any advice?
