[Johnathan Clarke]

Hi Everyone,
i am getting an error unable to create wintun interface my Google Fu
has not given me many results that look like they have an answer i
need.
Where should the WinTun files be located? should i replace them with
the files from the wintun project page
https://www.wintun.net/

is there away to re register the Tun Device?

Your log indicates that the adapter device was created, but has a problem code with a STATUS_SUCCESS problem status. I have reintroduced the problem code check in https://git.zx2c4.com/wintun/commit/?id=2881164bff0e819f6b0b6d5fc5d3a185ecb47457. This should evaluate the Wintun adapter state with better precision.

Meanwhile, can you please examine your C:\Windows\INF\setupapi.dev.log file for clues. (Note that a 0x1f/0xc0000495 problem code/status is normal when Wintun adapter is created early at boot. Hence the STATUS_PNP_DEVICE_CONFIGURATION_PENDING check in the code.)

Hello Everyone.

I believe I've encountered the same issue. My Wintun interface failed
to boot up, and I found a warning sign on the Wintun adapter in the
device manager.

After digging into the setupapi.dev.log, I found that it's the same
error message as Johnathan's.

!    dvi: Device pending start: Device has problem: 0x38
(CM_PROB_NEED_CLASS_CONFIG), problem status: 0x00000000.

I noticed that the Cisco AnyConnect secure mobility client got a
virtual adapter installed in the system, which instance id is also
'ROOT\NET\0000'.
Hopefully, this will be helpful.

Regards,
Hank Bao
