I've search for solutions in this thread, but without luck : topic7663.html

Open VPN was working fine, until I updated my Samsung ATIV to Windows 8.1 Preview.

I tried uninstall, re-install, TAP-uninstall, TAP-reinstall, devices management update plugin, deactivate, reactivate, reinstall driver from location, deltapall, etc.

I end up with the following trace :

I can't remove TAP-Windows driver from device managements, neither get it working.

I've been trying with 2.3.2 64 bits windows installer.

Any help will be appreciated...

Thanks

To the newbies that will follow behind me, here is how I solved the problem :

- granted administrator privileges to C:\Program Files\TAP-Windows\devcon.exe
- set compatibility mode to "Windows 7" (not sure it was usefull though)
- run C:\Program Files\TAP-Windows\deltapall
- run C:\Program Files\TAP-Windows\addtap

Still, I have no idea why upgrading Windows failed the device.

In my case, it was enough simply enable TAP device in device manager.
I hope it will be helpful for somebody.

Hi,

In my case problem is bit different, I am able to connect to Open VPN successfully and TAp driver is also coming up. But within few seconds my wifi interface goes down hence vpn connections goes into reconnect state.

The problem I am facing is with windows 8.1 pro and with wifi only. It seems like windows 8.1 is not allowing two interface to be connected (Tap and wifi).

Still not able to sort out the issue

... kindly help
