But obviously you are going to be missing a network interface. They are going to get installed, only this time you are not going to receive an error any longer. and after that select to not install the TAP-Windows6 and Wintun drivers. This can be done in two ways:ġ- You can simply open up the installer msi but this time choose to customize the installation. So if you somehow could get it installed your problems would go away. Here is what to do: The device being installed which fails obviously is the network adapter, for the new Wintun device. I decided to remove it using Windows 10 device manager including the driver.īut after that, when I tried to reinstall OpenVPN client 2.5 there was this error message:ĭiInstallDevice failed Error - 536870397:Īt first I was frustrated, but after I looked around a bit I figured it out and now I am sharing it here in case anyone else is having similar issues or problems.

Consequently, I uninstalled version 2.5 which I had just installed, but still the 'OpenVPN Wintun' device remained behind.

Surprised by this I decided maybe this was because I have to do a clean install. On my machine I had version 2.4 previously installed I downloaded the client installer for version 2.5, after I installed it I noticed that another network adapter was also installed alongside TAP-Windows Adapter V9. Hi there everyone today I decided to move from version 2.4 to 2.5 but there was a problem with the installation.
