I updated my Hamachi on Server 2008 R2. the old one was working perfectly. Now, there is no hamachi adapter and I'm getting the network adapter error. This is NOT firewall as my firewall is currently disabled. How do I get the installer to put the hamachi adapter back?
I do have the same problem since updating to Hamachi² (188.8.131.52). I am using Windows Vista x64 (German) with Service Pack 2 installed. I tried to fix it by uninstalling and reinstalling hamachi, but there still is no hamachi network adapter.
I discovered that hamahi interface is not linked to TCP/IP v4 protocol. Unfortunately, when I try to link TCP/IP protocol to interface - windows says, that other applet is open in that time, and discard any changes.
After testing many conceptions (mainly based on register modifications), I decided to reinstall windows and ... on clear system problem doesn't occur.
I have tryed this solution as first. I think i'ts shomething with operating System settings - maby some other VPN software (in my case I' had Cisco VPN, Open VPN, Checkpoint, TeamViewer, MS VPN (IPsec) installed
