2.6.3 Problem With TAP Driver Signature

[r4taw2mg]

Hi, I was just trying to install 2.6.3 MSI on Windows 7 (updating from 2.6.0). While trying to install the TAP-Windows6 driver I receive an error message that the driver has no valid digital signature. Being careful, I aborted the installation. Is there a problem with the installer?

Hi, thanks for reporting it. You can proceed with installation, if you check the driver version it should be be 9.24.6. I'll check signing part.

@r4taw2mg which version is that? 2.6.3-I001 or I002/I003?

It's I003.

I have rebuilt the driver packages (MSM), they now include the exact same drivers from 2.6.0. I have uploaded them to https://github.com/OpenVPN/tap-windows6/releases/tag/9.26.0, however I cannot build an installer package in GitHub Actions because of this vcpkg bug.

@r4taw2mg I have build the MSI with the new driver, could you please give it a try? OpenVPN-2.6.3-I003-amd64.zip

Should be fixed in 2.6.4-I001. @lstipakov, @r4taw2mg can you confirm?

[flichtenheld]

@lstipakov confirmed on IRC that the issue is fixed in 2.6.4.

I'm happy you guys still try to support Windows 7!

By the way, am I still able to utilise the Data Channel Offload (DCO) kernel acceleration support for Windows if I use the operating system windows 7 and in the openvpn installer only select to install TAP-Windows6, Wintun and hope for a performance increase?

No, DCO requires Windows 10 20H1 and newer.
