TAP-Windows adapter not found

[MrGeneration]

Hello,

I have been using openvpn for some years now and came to a point were I need to connect to 2 different OpenVPN-Servers.
For this I installed a second TAP-Adapter and then renamed both adapters to names I can remember better and put them together with dev-node into the to them belonging config.

The older one (that also uses the older adapter) works fine, the new one does not. OpenVPN says "TAP-Windows adapter 'ACT-VPN' not found" even though I can see it in my system. Google returned nothing useful for me - so I hope that someone can help me here.

I am using a Windows 8.1 Pro x64 Laptop with the current v2.3.6 x86_64
Here's the config(s), logfile of the broken VPN:

We have seen a similar problem here:

Also, you may have installed one version of openvpn over another.
Try unistalling openvpn completely (Backup your config files first!)
And reinstall only the newest version.
