Ошибка при попытке подключения к OpenVPN серверу.
Ошибка «All TAP-Windows adapters on this system are currently in use» означает что в системе проблемы с виртуальным Tun/Tap сетевым адаптером, который использует OpenVPN в Windows.
В моем случае он просто не появлялся в системе Windows7.
Для исправления проблемы нужно переустановить драйвер виртуального адаптера.
Полностью удаляем драйвер. Открываем папку C:\Program Files\TAP-Windows
Нажимаем правой кнопкой на файл Uninstall.exe и выбираем Запустить от имени администратора.
Качаем Tap драйвер с OpenVPN репозитория и устанавливаем его с правами админа (правый клик на файле > Запустить от имени администратора )
После всего обязательно заходим в Панель управления\Сеть и Интернет\Сетевые подключения и проверяем там наличие TAP-Windows Adapter.

TAP-Windows Adapter is a network driver through which VPN services can allow your computer to connect to the VPN servers. Unfortunately, when connecting to a VPN, you may get the error that says,
There are no TAP-Windows adapters installed on this system.
Similar to the All TAP-Windows adapters on this system are currently in use error, this is not a crucial error, and the message states precisely what is wrong with the connection.
You can repair this TAP driver issue in three stages. The troubleshooting guide will list these stages and explain how to go about them.
- Restart the TAP-Windows adapter.
- Reinstall TAP-Windows drivers.
- Create a new TAP-Windows adapter.
Below is the full guide. I advise that you follow the steps in the order in which I’ve listed them here.
1] Restart the TAP-Windows adapter
The recommended way to fix this TAP driver error is to restart the TAP adapter. To do this, follow the steps below:
Right-click on the network icon on your taskbar and click on Open Network & Internet settings.
In the network status window that opens, select Change adapter options.
Find the TAP adapter on this screen. They are named differently based on the VPNs, so you can only look out for an adapter or connection with TAP in its description.
Right-click on the TAP and hit the Disable option.
After disabling the network adapter, right-click on it again and re-name it.
2] Reinstall TAP-Windows drivers
If you restart the TAP network adapter and still receive the error, then you should go ahead and reinstall the TAP drivers. You can do this in several ways.
First, you may uninstall your VPN software and reinstall it again. Ensure that you restart your computer after uninstalling the VPN.
When the machine comes back on, install the VPN software, and the installation will most likely come with TAP drivers.
Press the Windows key + R combination, type devmgmt.msc in the Run dialog box and hit ENTER.
In Device Manager, expand the Network adapters section and find the TAP-Windows adapter listed under it.
Right-click on the driver and choose the Uninstall device option.
Complete the uninstall process by following the on-screen instructions.
With the driver uninstalled, launch your VPN client, and it may ask you to install the missing TAP network drivers.
Some VPNs will only prompt you that the driver is missing. If this is the case, you need to download the driver off the internet or download the VPN client’s latest version.
Alternatively, you download the TAP-Windows driver software and install it on your computer manually. If you’re unsure where to download the drivers or even how to use them, this guide is a great starting point.
3] Create a new TAP-Windows adapter
Windows says that it couldn’t find TAP-Windows adapters on your system. The most straightforward method is to create a new TAP-Windows adapter.
Windows creates a new TAP-Windows adapter when you create a hyper-machine or connect to a VPN service.
Also, note that you can have only one TAP-Windows adapter active at a given time.

Question
-
There are no TAP-Windows adapters on this system. You should be able to create a TAP-Windows adapter by going to Start -> All Programs -> TAP-Windows -> Utilities -> Add a new TAP-Windows virtual ethernet adapter.
This does not work in Windows 10. Any ideas?

On some versions of windows, specifically certain build of Windows 7 64-bit or when you have other VPN software installed some clients may experience the following error:
«There are no TAP-Win32 adapters on this system. You should be able to create a TAP-Win32 adapter by going to Start -> All Programs -> OpenVPN -> Add a new TAP-Win32 virtual ethernet adapter.»
To resolve this, open notepad as administrator and paste in the following:
tapinstall install OemWin2k.inf tap0901
And save this file to your vpnsecure program directory usually in C:\Program Files (x86)\VPNSecureMe\driver\32\forceinstall.bat or C:\Program Files (x86)\VPNSecureMe\driver\64\forceinstall.bat depending on whether you use 32 or 64 bit windows.
Then just run that batch file as administrator, the correct TUN adapter driver will be installed and the problem will be solved
Alternative 1
You could install the latest version of OpenVPN GUI, which would also force this driver to be installed. Then you can use our application as normal.
http://openvpn.net/index.php/open-source/downloads.html
There is an alternative OpenVPN portable project, that has a different way of installing TAP adapters — http://sourceforge.net/projects/ovpnp/
Alternative 2
You could uninstall this version of our application completely and install an older version that doesn’t have this issue : http://vpnsecure.me/files/VPNS_0.9.3.0.exe
Alternative 3
There is a registry key that some users have found interfering with the TAP driver installation. If you’re not comfortable with regedit, please contact our support staff for assistance — you can easily break your pc here!
1. Backup the registry (regedit > export)
2. In start>run>cmd>regedit, browse to the following registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network
3. Rename the key called Config to Config.bak
After renaming this key, re-run our windows openvpn installer and it should be able to install the TAP adapter this time.
