outline-apps: Installation error in Windows 11: TAP device failed to install with error code 1
When installing Outline in Windows 11 I get “TAP device failed to install with error code 1” error message during installation (image of the error message below).

Even though I get the error message the Outline Client is still installed and I can run it, but when I try to connect to the server I get an error message “Sorry, it looks like Outline is not properly installed. Please try installing it again. If that doesn’t work, please submit feedback through the app.”
I have read https://github.com/Jigsaw-Code/outline-client/issues/1007 so I executed Get-NetAdapter command. However, the output didn’t have any TAP Windows Adapter V9 entries or anything else with a TAP. That hints the issue is different and probably related to the TAP adapter installation.
Does anyone know what that error code 1 means? Is there any verbose installation method to get more information about the failure? And most importantly, is Outline supposed to work in Windows 11?
System details:
- Outline Client Version: Windows 1.6.0
- Operating System: Windows 11

After the update, the same problem occurred, removing the outline and rolling back to another version helped: https://github.com/Jigsaw-Code/outline-apps/releases/tag/v1.10.1
Root cause for v1.13.0 installation failure: OemVista.inf should be
CRLFline ended instead ofLF. We made a change two months ago which caused this regression: https://github.com/Jigsaw-Code/outline-apps/pull/1913 . Will fix it soon.I have same problem. I have run on Windows 11 Pro(ARM) , run on Macbook M1 through Parallels
I had the same problem, it helped. Thanks
The same issue happens with the Outline 1.13.0 installer from getoutline.org. It creates a couple Unknown Devices in device manager and exits the installer. Running Windows 11 Pro x64 build 22621. Workarounds mentioned previously do not resolve.
yeah, it’s working
hi
remove all TAP-Driver from device manager on “network adapters” and reinstall outline
Same problem here.
Windows 11 Pro (ARM) runs on MBP M1 with Parallels Desktop.
