What is the Crucible Launcher?
The Crucible launcher is the hub for the Crucible apps. It is one Windows app that downloads, updates, and launches every Crucible tool, so you install the launcher once and pick the apps you want from inside it.

The launcher runs without a license. A subscription only unlocks the paid apps it hosts, currently just Crucible Heightmap; the launcher itself and Crucible Local Server need no key. You activate a Heightmap subscription in the launcher’s Account panel and it unlocks that one app. See activate a license and manage your account.
