Well, welcome. I have this problem for a long time. What I did do: and updates included Windows, and reinstalled the program several times, and much more. But the problem does not disappear.
The point is this: I install Hamachi; along with it installed 2 network adapter with the same name (Hamachi Network Interface and Hamachi Network Interface # 2), both of which do not work (yellow sign near them). The adapter does not appear in the center of the Network and Sharing Center.
What I was trying to do:
1. reinstall Hamachi
2. Use the "legacy hardware" (Device Manager)
3. Includes Windows Update
4. Go to services.msc, which did not find the item Network Connections
5. Did the first 2 points, disable the firewall and disable antivirus (later altogether deleted it)
For reference:
I have a Windows 7
In Tunngle I also have a problem: steady yellow snout preventing connect, though the adapter is installed (suddenly help)
Help me find a solution to this problem.
