I had a corrupt Smart Security 4 on this computer that would not unistall. I purchased SS5 yesterday and tried to install (Win7 32bit). After dozens of attempts, it fails every time. Errors messages include "Computer has not been restarted after a program uninstallation...." Not true at all. I've rebooted many times! I logged in regedit and got an error code of 2826. I submitted a complaint thru Eset but haven't heard back. I've reviewed many of these posts and nothing seems to work. I even tried the Safe Mode uninstall to clean out any remaining AV files. Any other suggestions would be appreciated.
