I tried installing old versions (the .pkg) versions as all of the .app versions seem to give the same error message.
None of them are able to run on El Capitan for more than 5 seconds, and either time I press the "check for updates" to maybe trick Hamachi to update correctly from the old one to the new - the program crashes.
Is there ANY way to get Hamachi on OS X El Capitan? I've tried everything. Tried all of the old installers.
