Just bought a 3 seat subscription to Internet Security Plus. Activates correctly on my Windows 10 PC where I originally installed trial software. Same keycode activates correctly on a 2nd Windows 10 PC that had never had trial software installed. On 3rd Windows 10 PC that had trial software installed with a different keycode, the purchased keycode won’t activate. I get an error that the keycode cannot be activated. I’ve uninstalled the trial software, rebooted, scoured the computer for any folders, config files, and registry keys that could be remembering that the trial was installed and can’t find anything.

Thanks again, Keenan. I very much appreciate the follow-up. I just figured out the problem and the third seat is now working correctly. I’ll share the fix here in case this may be helpful to others with this problem.
It turns out there was a registry key left over from the trial software that was not removed by an uninstall. The path to the leftover key is this: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\webroot. Just deleted that whole key and related subkeys, then rebooted. Installation and keycode activation worked perfectly after that.
If/when I hear back from tech support, I’ll share this with them as well. The uninstall process should remove that registry key automatically. I found this by doing a Find within registry editor for the working keycode on my Windows 10 PC. For some reason, on a paid version of the installation, the key is called WRData but on a trial version the key is called webroot.
