Re-install OpenVPN

We suggest that you download a free application removal tool called Revo Uninstaller. This is a great tool to remove applications, leftover files and broken registry keys.

Once OpenVPN has been removed, please scan for leftover files and registry keys. Remove them and restart your computer.

Finally, download the latest version of OpenVPN from the official website and install it on your computer.

Best Free VPN Provider

If you’re looking for a secured and trusted VPN provider, we would recommend you that you try free VPN VPN client app supports OpenVPN in their app so you don’t need to configure the VPN connection manually and their app is so easy to use.

The free service provides the same level of protection as the paid service. They don’t keep logs of their user activities and there are no ADs!


Adding/re-enabling the OpenVPN TAP adapter should be pretty straight forward but often, VPN providers don’t update the OpenVPN client on their site which can lead to such issues.
