Hamachi: Failed to connect to the engine
After getting the Hamachi 2 update (without a prior notice, nicely done… No more auto update if they continue to break stuff) I started to notice a bunch of XPs receiving this error after a reboot: Failed to connect to the engine.
Hamachi is auto started, at boot, because we have a shortcut in the startup folder. No other way to auto start the free version (as far as I know).
