I upgraded to Windows 8.1 yesterday however my Hamachi network adapter disappeared from the list of network adapters.
I've tried reinstalling Hamachi but the adapter still doesn't appear anymore.
I realized Windows 8.1 is new but I'm curious if anyone else has experienced something similar after this latest upgrade.

Yes, I've run into the same issue upon upgrading to Windows 8.1.
Me three, any solutions yet?
I managed to solve my problem.
I reinstalled hamachi and that created the network interface again, but the service didn't start, turns out the registry was missing some values, I did the following:
add EngineConfigDir string value to the registry:
for windows 8.1 32 bit HKEY_LOCAL_MACHINE\SOFTWARE\LogMeIn Hamachi
for Windows 8.1 64 bit HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\LogMeIn
Create folder C:\Windows\System32\config\systemprofile\AppData\Local\LogMeIn Hamachi and add that folder to the EngineConfigDir value
this also fixed problems on a WHS 2011 machine.
I had this issue as well, I used the uninstaller to remove everything but user settings. Choose the remove option, not the repair option. Afterwards I reinstalled Hamachi, it started up, and all is well again.
Also, my registry used a different path for the EngineConfigDir:
C:\Windows\ServiceProfiles\LocalService\AppData\Local\LogMeIn Hamachi
This happens when you upgrade your OS with older versions of Hamachi. The reason this occurs is that the location we used to use does not carry over properly when updating, so everything gets thrown in the windows.old folder. The latest version of Hamachi does not encounter this issue.
Generally speaking, a reinstall is the best option. Barring that, however, you can run the following commands from the command prompt within the Installation folder:
hamachi-2.exe --upd-tap
hamachi-2.exe --add-tap "Hamachi"
Then restarting the Hamachi Service.
When entering the second command (hamachi-2.exe --add-tap "Hamachi") I get the following error:
"Error while installing hamachi: SetupDiCreateDeviceInfo failed with code 00000005"

Thanks to Geos. The one with adding values to registry works for me after upgrading to win 8.1 64bit on Asus laptop.
Just a simple uninstall & reinstall without removing the settings did the trick for me.
