Client installation on Windows 7 doesn't worked

Hello,

Error:

Remote installation failed on the device: Wintun error: Failed to install driver: The publisher of a signed catalog Authenticode(tm) is not yet defined as approved. (Code 0xE0000242)

The installation under Windows 10 works well, but not under Windows 7.

WINDOWS 64-BIT MSI INSTALLER "openvpn-2.5.1-i601-amd64.msi"

I'm trying this out :

Set it to "Ignore":

User Configuration ->Administrative Templates -> System -> Driver Installation -> Code signing for drivers

The attempt above did not work, the problem persists.
The problem comes from the signed driver "TAP", Windows 7 warns me that it is not signed and therefore does not want to install it.

Yes, my install of OpenVPN on Windows 7 shows that the TAP driver is not Digitally Signed.

Okay, do you have a solution for deploying OpenVPN on Windows 7?

I would think that you can either drop your requirement for fully digitally signed device drivers
or wait for Openvpn to fully digitally sign the TAP driver ..

Or do what I did and DITCH Microsoft completely ..

I don't want the TAP driver to be signed but I want to deploy OpenVPN on Windows 7 computers.

I think I'm not the only one trying to do this?

you need to install old version as 2.3 so you can use it, old windows dont have support new openvpn that is true and nothing can make it work on win7 , dont take time to install and should read requirement before doing so.

I was able to get OpenVPN to work regardless of the version on Windows 7 but with a manual installation.
I had to accept the use of the unsigned TAP driver for it to work.

Except that by deployment, I can't install the TAP driver.

"Wintun error: Failed to install driver: The publisher of a signed catalog Authenticode(tm) is not yet defined as approved. (Code 0xE0000242)"

I have as explained in other posts, tried the GPO to ignore the fact that a driver is not signed, but no change.

Thanks for your help.
