@wecloud2008 this is an ongoing issue which we're working hard at to fix. This can sometimes also happen if other VPNs are installed on the machine.

@wecloud2008 we released a new version of the Windows client yesterday, try getting a fresh download of the client and see if that works for you? We don't think this is the final solution but hopefully it's a step forward.

I am still having this problem on windows 10. It was working two weeks ago now i am getting TAP error when trying to install the client. Is there any way we can reset all TAP device settings or are there any manuel steps we can take to bypass this issue?

Since i am using this on my second laptop, I used Windows's "Settings -> Recovery" option to reset the laptop. Now it works. But it will delete some of your apps. So it might not be an option for everybody.
Looking forward for a reliable solution on this...

@ymn @wecloud2008 if you email Support@getoutline.org you can get some instructions about removing the tap drivers and other support

This is from our support person:

TAP-Windows Adapter V9 is a network driver that allows VPN to connect to its servers. The default installation location is C:/Program Files/Tap-Windows, and it appears in Device Manager under Network Adapters category. Unfortunately, some users reported that they have connection problems when TAP Windows Adapter V9 is enabled, and even if the device is disabled, it does enable itself after a reboot of the computer.
If you are having problems with the TAP adapter we suggest to first restart it the following way:
In the taskbar search box, type in Control Panel
Then go to Network and Internet Network sharing Center
On the right side of the window, click on Change adapter settings
Right-click on the local area connection which is using TAP Windows Adapter V9 and select Disable
Wait a few moments, right-click it again and pick Enable
Right-click on the Start button and select Device Manager
Under Network adapters select TAP-Windows Adapter V9
Right-click on it and press Uninstall device
Follow the on-screen instructions until the process is finished
If you cannot connect to the internet while using the VPN, try re-installing the TAP Windows Adapter V9:
Under Network adapters select TAP-Windows Adapter V9
Right-click on it and press Uninstall device
Follow the on-screen instructions until the process is finished

Note: You may have to temporarily disable any Antivirus or other real-time threat monitoring software you may have on your machine.

Issue still not resolve?

[JonathanDCohen]

I'm sorry that didn't work. This is an open issue that we've been working tirelessly to fix. The issue is that netsh isn't able to find our device, even after we wait a while for it to show up on the interface list. The API here is relatively annoying and hard to use, and also hard to test as we've never been able to consistently recreate this error on any of our Windows machines.

I just want to mention, that this new update does actually fix the problem of renaming the TAP adapter. I have tested it on 2 windows machines, the version before this update, there is sometimes the issue with script not able to rename tap to "outline-tap0", this new script does fix that. I was able to fix it with pulling the new add_tap_device.bat and find_tap_device_name.bat, and build&reinstall.
My problem 1 month ago, i could not even rename manually the adapter, so i think that problem was something different, fixed it by reinstalling whole windows.

Hi, I am also having the issue. Have tried the steps listed on the troubleshooting page but am still not able to install the Outinline / TAP device

[sanvit]

This seems to happen if you already have TAP driver installed by other software (it was OpenVPN GUI for me).
Deleting ALL TAP drivers on Device manager (Device manager > Network Adapters > TAP-Windows Adapter V9) and re installing Outline fixed the issue for me.

@fortuna what do you think?

[alexlii1971]

I am in China, and I got same issue on window 7 with outline-client 1.6 version

After check network configuare on outline-tap0, I found it automatically use dns address: 1.1.1.1, 9.9.9.9

Is that might reason?

here is the screenshot:

[fortuna]

We will release a new version with a new network stack written in Go that may address some of these issues.
/cc @jyyi1 for awareness

@alexlii1971 we need to specify a DNS resolver because your local ISP resolver may be censoring the results.

[alexlii1971]

If any local antivirus or firewall is working, like 360, lenovo PC security and Tencent security, outline client installation will be completed, but client will not work even if turn off them. At least, I tried a lot, but still can not fix it.

Those so-called security software are actually also working as inspection of anti VPN.And you will note that if you have a try.

But outline works well on Mac and other devices like iPhone or Android.

[alexlii1971]

uninsall it, and reinstall the old version:

https://github.com/Jigsaw-Code/outline-client/releases/tag/windows-v1.2.27

this issue is related to Tap adapter. if your client does not work, mostly, the Tap adapter is not installed by some reason, like local antivirus software or some security software.
