Most common issues can be solved here: https://support.logmeininc.com/hamachi/help/troubleshooting-failed-hamachi-client-setup-hamachi-c-ha...
Otherwise, I found this manual route to work for me:
** In a worst case scenario, where Hamachi connection isn't listed at all, then a full re-install may be needed.
Hope this helps,
this is the error message that i always get when i boot hamachi2
my internet is fine so i dont know why hamachi2 cant connect to whatever it needs to connect to
Please create a ticket here...
...and report the results in this thread.
i figured out what was causing the message to come up
hamachi now uses 2 processes to increase network performance
well, the system process that comtroled the engine didn't boot when it was told to so the message came up
i installed logmein free and it seemed to have solved the issue
