I recently re-instaled windows 7 pro 64 bit SP1 on my computer 2 weeks ago, due to a failed hard drive. I reinstalled Nod32, and it was working fine, except for an idiotic popup continually prompting me to enable livegrid, which I did not want to enable. I read that uninstalling ESET and re-installing the latest version will eliminate the problem; after uninstalling, I tried to re-install, and now I get a message that I can't install Nod32 because my operating system is no longer supported. It was fine earlier today other than the nagging livegrid popup, so why won't it install now? The webpage still indicates nod32 will run on Win7.
