All programs must be closed before installation?

All programs are closed! Yet, it keeps telling me all programs must be closed. I click "Close all programs now" and it thinks for a minute before telling me all programs must be closed again. FRUSTRATED!

Reboot. If that fails, reboot into Safe Mode, and try the install from there.

Any add-on anti-malware, add-on anti-virus, add-on VPN clients, add-on cleaners, or such?
