Re: Have to reinstall Hamachi after every update

As already stated in a previous thread, the best current workaround is to refresh the Hamachi service. 

net stop "LogMeIn Hamachi Tunneling Engine"
net start "LogMeIn Hamachi Tunneling Engine"

Either enter the above in a Command Prompt with administrator privilage or, more simply, make a batch command file that runs these 2 lines. Make sure your *.bat file is run as administrator.
