Hi @GaurangTandon, it sounds like there might have been an issue with the policy.

A couple of things to check:

At "System Settings > Policies" do you see the policy as installed?
At chrome://policy, do you see ExtensionInstallSources with a value that includes localhost?
At chrome://policy, do you see ExtensionInstallAllowlist with a value that includes an extension ID?

Let me know how you get on 😃

@oliverdunk I have the same issue - I have tried using a live domain as well and confirmed all settings. When I allow the CRX to be downloaded it does let me install it but accessing the CRX URL directly gives CRX_REQUIRED_PROOF_MISSING

Chrome on Mac - Version 126.0.6478.116 (Official Build) (arm64)

I'm seeing the same on Windows as well (and registry settings are correct).
