One day ago I installed the mb3-setup-consumer-3.1.0.1716.exe program; after reboot, I received a Malwarebytes dialog "Unable to connect the server."
I restored my system from a backup image.
After browsing the forum, I decided to give another effort:
Quit Malwarebytes from the tray icon.
Ran the mb-clean-2.4.1.1015.exe program; when it completed, a reboot dialog request showed - I rebooted.
After login, the dialog requested "Would you like to download and install Malwarebytes v3.x?" - I clicked on No. The program exited.
Ran the mb3-setup-consumer-3.1.0.1716.exe program; installed successfully. I had to reactivate my license.
Ran a scan. Seems OK.
Rebooted. Seems OK.
