logmein-hamachi: System extension cannot be viewed

[wadewilliams]

Thanks for your time. Trying to be helpful here & I'm happy to contribute fixes.

Description of issue

• Attempting to install logmein-hamachi on OSX 10.11.6
• Everything appears to to go well until I get this error:
  
• I noticed this output during the brew cask install logmein-hamachi:

==> Can't open CFBundle for /Library/Extensions/ham.kext.
==> Can't create /Library/Extensions/ham.kext.
==> + kextunload /Library/Extensions/ham.kext
==> Can't open CFBundle for /Library/Extensions/ham.kext.
==> Can't create /Library/Extensions/ham.kext.

• I can open hamachi but it crashes after interacting with the application.
• I have been using hamachi on my system, and re-installed it via cask today while trying to learn more about the homebrew/caskroom ecosystem - I probably broke something, somehow :)
• I understand the output of my brew doctor - I was planning to hack on homebrew for the next month or so before updating to macos/xcode8, hoping that the brew doctor output is not critical ATM.

Thanks for the complete bug report.

Looks like it's a confirmed bug: #24786

Closing as duplicate, but the original bug report issue will stay open.

I'm getting the same issue as well. I've been having this problem for at least the 3 day after i updated to sierra. I tried updating to sierra again i reinstalled hamachi it worked for a while until i restarted my computer, There was a new update that i couldn't install because of some error, I used hamachi in the past many times before with no errors or bugs until sierra.
