Hello, I came across a situation - when I connect LogMeIn Hamachi, which is installed on Windows 7, to the network, the computers on the network are not accessible, and a yellow triangle with an exclamation mark is drawn against them. I want to show how you can fix this error.
If you go into the node connection details, an error will be written next to the VPN status parameter.
If you go to the settings, in the VPN domain the status information shows an error - Failed to connect to the network adapter. The peer is not reachable via VPN.
In my case the problem was with the installation network driver Hamachi. If you go to the device manager (computer properties - device manager), you can see an exclamation mark in a yellow triangle for the Hamachi Network Interface driver. If you go to the properties of this driver it will be written that the driver does not have a digital signature.
Because of this, the system does not have a Hamachi network interface, and Hamachi cannot connect to computers on the network.
To fix this, you can take a difficult and simple route.
Difficult - put the system into test mode and turn it off group policies mandatory verification of the digital signature of drivers. But I didn’t do that, and I don’t advise you to.
Simple - download Hamachi version 2.2.0.328 - Hamachi 2.2.0.328
After Hamachi 2.2.0.328 is downloaded, you need to remove the version that you have installed. And just install the version that was downloaded. In this version everything is fine with digital signature driver, and after installing it everything worked for me.
After starting the program, you can update it from the program itself (help - check for updates), or you can download latest version from the developers site. When you run the installer, the program will be updated. And there should be no problems with the driver and connecting to computers.
By the way, I installed the latest version of the program on Windows 10, it worked fine for me, but if suddenly you have the same problem that I wrote about above, then you can try installing version 2.2.0.328.
With it, I had a situation where the driver in the device manager works fine, there are no exclamation marks, but there is no network interface in the network and sharing center. A simple reinstallation of LogMeIn Hamachi helped, meaning this version needs to be installed 2 times. After which everything works fine.

Are there any unresolved problems?
– special software that allows you to build your own secure networks via the Internet. Many gamers download the program to play Minecraft, Counter Strike, etc. Despite the simplicity of the settings, sometimes the application has a connection problem with network adapter, which can be fixed fairly quickly, but requires certain actions on the part of the user. Let's look at how this is done.
Now we will go to network settings and make some adjustments to them. Let's check if the problem is still there, if so, we'll update Hamachi to the latest version.
Network connection settings on your computer
1. Go to “Control Panel” – “Network and Internet” – “Network and Sharing Center”.
2. On the left side of the window, select from the list "Change adapter settings".
3. Click tab "Additionally" and let's go to "Extra options".
If you are missing a tab "Additionally", let's go to "Arrange" - "View" and click on "Menu Bar".
4. We are interested "Adapters and Bindings". At the top of the window, we see a list of network connections, among them is Hamachi. Move it to the beginning of the list using special arrows and click "OK".
5. Restart the program.
As a rule, at this stage the problem disappears for most users. Otherwise, move on to the next method.
Update problem
1. Hamachi provides auto mode updates. Very often, connection problems arise due to incorrect settings in this part of the program. In order to fix it, find the tab in the main window “System” – “Parameters”.
2. In the window that opens, on the left side, also go to “Options” – “Advanced settings”.
3. And then in "Basic settings".
4. Here you need to check the box next to « Automatic update» . Restart your computer. Make sure the Internet is connected and working. Once started, Hamachi should automatically detect if there are updates and install them.
5. If the checkmark is present and a new version was never loaded, go to the tab in the main window “Help” – “Check for updates”. If updates are available, update manually.
If this does not help, then most likely the problem is in the program itself. In this case, it makes sense to delete it and download the latest version from the official website.
6. Please note that standard removal through "Control Panel" not enough. Such uninstallation leaves behind various “tails” that can interfere with the installation and use of a newly installed Hamachi. You must use third party software to complete removal programs such as Revo Uninstaller.
7. Open it and select our program, then click "Delete".
8. It will start first standard master uninstallation, after which the program will offer to scan for the remaining files on the system. The user needs to select a mode, in this case it is "Moderate", and press "Scan"
After this, Hamachi will be completely removed from the computer. Now you can start installing the latest version.
Often, after the steps taken, the connection is made without problems and no longer bothers the user. If things are still going wrong, you can write a letter to support or reinstall the operating system.
