Downloaded this program for the first time and after i press "connect to recommended server" and the "tunnel drivers" are installing, the process is aborted and this message apears: "VPN network adaptor not found: install fail (0901)". After three seconds it restarts, and the message reappears, over and over again. What to do?

Hi, just downloaded Eddie, I log in and when I click on servers it comes as: Installing tunnel driver and Driver installation failed. Any suggestions please?

Hey guys, So I spent the last few hours or so trying to figure out this bug I was getting while starting AirVPN, and I wanted to share my results in case some poor soul comes across this seemingly obscure situation in the future. I'll do bullet points as to try not to talk too much: AirVPN was working greatI installed Visual Studio 2013 ProAirVPN then stops working immediately after installI notice there are a few new network adaptersMUCH MUCH later I found that by uninstalling a feature called Hyper-V, which (I'm only guessing) came with Visual Studio, did the "Driver installation failed" error stop and I was able to connectSo yeah... I spent some time digging through the source and then utilizing the newly installed VS to compile and debug the lines surrounding the error. Well, I had never heard of Hyper-V before and so all I wanted was AirVPN to work with my current adapter situation. I thought it was because one C# library function was returning adapter descriptions that AirVPN wasn't expecting. But even when I tried forcing it to one of the 10 available adapters (some of which were labelled TAP) yieled pretty much the same result every time. I now think it was due to the bridging that Hyper-V forced upon me, and since my issue is resolved I don't care to look into this further. Tl;dr: Check if Hyper-V is installed in your Windows features. If so, uninstall it, reboot, and re-run AirVPN. If Hyper-V isn't installed try this: https://airvpn.org/topic/13126-driver-installation-failed/ Here's what my adapters looked like before uninstalling Hyper-V: Here's an image that shows how to uninstall Hyper-V:
