Received this on new laptop my company issued. Booted a couple of times without issue, then this error message popped up:
"TUN interface creation failed: cannot acquire TAP handle"
Using Windows 10 Pro.
the following updates were installed along the way before I saw the problem:
1. Security Update for Adobe Flash Player for Windows 10 Version 1607 (for x64-based Systems) (KB3201860)
2. Update for Windows 10 Version 1607 for x64-based Systems (KB3199986)
3. Feature update to Windows 10, version 1607
I'm on the east coast and our IT support is ont he other coast. Trying to debug since they won't be in for hours...

Re: TUN interface creation failed: cannot acquire TAP handle
try reinstalling openvpn , after you remove it first and maybe clean the registries
unfortunately windows 10 updates tend to mess up things a lot more often than older versions of the OS.

Re: TUN interface creation failed: cannot acquire TAP handle
I know this is an old post and it has been resolved by re-installation, but check to make sure that the TAP adapter is enabled. If it isn't, Windows can't pass back a handle to OpenVPN.
