Original GitHub issue: https://github.com/netbirdio/netbird/issues/4023

Is your feature request related to a problem? Please describe.
Currently, the MSI and EXE installers for Windows don't seem to be signed in the same way that the actual executables are. Everything mostly still works, but it does cause a higher rate of issues with computers that have an EDR or company policies applied.

Describe the solution you'd like
Apply a signature to the installers in the same way as with the win executables

Describe alternatives you've considered
Currently, we sign it ourselves

Additional context
This is very much nice-to-have more than need-to-have, but since you seem to have the EV certificate in place adding the signature before publishing the Windows clients shouldn't be overly complicated.

Also want to add: Great product, you've done amazing work with this so far. Thank you!

@ephb commented on GitHub (Feb 27, 2026):

I want to second this request.
This is really cumbersome as we also now need to sign the installer ourselves, as unsigned code can not be run in our company.

While the installer is signed the signature is not based on a certificate authority that is trusted on Windows by default, showing Windows defender warning.

One solution would be to sign with Azure app signing.

That's interesting because the command is the same on both signatures.

Upon further investigation I noticed the application is signed the same, but windows does not bring it up again, when the installer was signed. Overall the current Root CA is insufficient for strict environments.

@scheibling commented on GitHub (Mar 6, 2026):

@ephb That one is strange though, the issuing CA for SSL.com EV Code Signing Intermediate CA RSA R3 is SSL.com EV Root Certification Authority RSA R2, which is included in the Microsoft Trusted Root Program.

Can you have a look at the certification path to see what it resolves to, or if it just fails to resolve the chain?

With that said, I haven't run into the issue lately on my end, so it might already be resolved. The ones I tested just now all worked in the enterprise environment I have access to.

@scheibling you are right. It is trusted in my personal PC but somehow our domain does not trust it.
I will investigate the origin of that issue and then report back to not confuse others with what I said earlier.

@scheibling commented on GitHub (Mar 17, 2026):

Right, after having looked into this a little more it looks like some of my domain-joined PCs are experiencing the same issue (both Intune and On-prem-managed devices).

The problem arises from a registry value:

HKLM\Software\Policies\Microsoft\SystemCertificates\AuthRoot\DisableRootAutoUpdate

This key is normally used when you have your own internal CA distribution method and don't want to accept auto-updates for trusted root certificates from Windows Update, but in most cases this should not be enabled. For some reason, it was enabled on some machines by default. Why I haven't quite figured out.

Normally, on first sighting of a CA from the trusted roots list it will be imported into the Windows Trusted Root Certification Authorities store. When the key is enabled, this does not happen automatically.

Some background: https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/setup-migrate-backup-recovery/connectivity-issues-digicert-global-root-g2-not-installed

Since the files are actually signed from Netbird, and this issue is a user/organization-level configuration issue, I'll close the ticket for now.

Thanks for digging.
I will change this in our domain.
