WiX v4 - A couple of FirewallException questions

[george7378]

Hey everyone - I'm using FirewallException in WiX v4 to add a rule for my app, like this:

<firewall:FirewallException Name="My rule name" Description="My rule description" Program="path\to\my\app.exe" Protocol="udp" Action="allow" Enabled="yes" IgnoreFailure="yes" Scope="any" />

Using this namespace: xmlns:firewall="http://wixtoolset.org/schemas/v4/wxs/firewall" and this package: <PackageReference Include="WixToolset.Firewall.wixext" Version="4.0.0" />

The FirewallException is within an existing component and has no child elements.

• When I try and compile my project, it fails with these errors:

If I remove Action and Enabled attributes, it compiles OK. When I navigate to the XSD (F12 in visual studio) they are there, so it's weird that the compiler rejects them.

• I'm having trouble creating outbound rules: when I add Outbound="yes" and run the installer, no rules are created and when I check the log, I see this:

ExecFirewallExceptions: Error 0x80070057: failed to add app to the authorized apps list

This happens whether I explicitly run as admin, or not. Is there any reason why it would fail? When I create the equivalent rule for the same .exe path using cmd it works fine.

Thanks for your help!

Regarding Action, can report that I face the same problem.
Seems like unexpected behavior because, according to the Firewall Schema, the attribute is expected?
Current "workaround" is obviously to remove it.

Do you get the same result under WiX v5.0.2?
In looking at the code for the Firewall Extension it does appear to capture both "Enabled" and "Action" attributes.

From the Git Blame these items were only added in WiX v5.0.0 rc1.
