In english:
Solution 1: re-enable the adapter
Open Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings.
Check description of network adapters to find the Tap-Windows Adapter.
Right click on it > Disable.
Right click again > Enable.
Solution 2: reinstall the Tap driver
Check if it is already installed by opening C:\Program Files\TAP-Windows
Right click on Uninstall and select Run as administrator
Download the Tap driver from OpenVPN repository and install it (right click on it > Run as administrator)
If you don’t have access to openvpn.org but you have our software, open our software location (where it was unzipped) and find the driver in the data\Tap\ subfolder.
