:smolnar What is the failure?

Comment 2

[Mike Hommey [:glandium]]

Artifact build is missing the desktop-launcher. See https://firefoxci.taskcluster-artifacts.net/RUqVl2eQSfaJrHZT4_cAPg/0/public/diff.html

Comment 3

[Mike Hommey [:glandium]]

it also doesn't have an extension.

OK. How do you get something into the artifact build?

Comment 5

[Chris DuPuis]

(In reply to Mike Hommey [:glandium] from comment #3)

it also doesn't have an extension.

There's a directory desktop-launcher, that contains an executable named desktop-launcher.exe.
