Hi,
Hamachi ARM-builds are still in beta and there currently no release date available for if/when they will go live. That would be why you can't find them.
We currently support x86/x64 platforms:
- .deb packages are compatible with Ubuntu 16.04 LTS
-.rpm packages are compatible with CentOS 7.2
They can be installed on other distributions, but it's not guaranteed nor supported.
I hope this information helps!
