Thank you guystooges.
I followed your procedure and downgraded to version 184.108.40.2069. It's fine but I get RPV error and cannot ping another peer online in the same group, bothe associated to the same logmein account.
Nothing change after I reboot both device.
I guess it's a tunnel issue to a too old version.
Then I decided to follow the procedure again with version 220.127.116.11.
It seems to work.
What is weird is hamachi kept all settings except auto-update turned to ON, then forced to create a new peer, get a new IP and join a network again.
The update to last version 18.104.22.1689 was done automatically before hamachi go online and I create a new peer.
So I am stuck withe the last version.
Having the issue that Hamachi most of the time goes online automatically, but sometimes it doesn't after a reboot. So it is not really dependable.
Is there a solution to force Hamachi to go online automatically every time?
Or does that work only with a paid account?
Hamachi version: 22.214.171.1246 on Win 7
