Download

Downloads open at launch.

Nothing can be downloaded today. The builds that exist are not code-signed and the catalogue is not public. When downloads open, this page lists each file with its version, size and SHA-256, and the launcher comes first. Until then the list hears first.

  1. Install the launcher

    One installer. It goes into your own user folder and never asks for administrator permission.

  2. Activate your computer

    Sign in once through the launcher. It registers this computer against your account — two are covered — and every Litesum application shares that activation.

  3. Choose your apps

    Install only the applications you want. Updates and the models some of them need arrive through the same signed catalogue.

Files

The launcher, then the applications.

Windows, 64-bit, throughout — Windows 10 or later where that has been tested, Windows 11 for Motion. Other platforms are intended where technically practical and are not offered: a platform appears here only once a build for it has been tested.

  1. Litesum Launcher

    Install firstVersion 0.2.1

    Signs your computer in, then installs, updates and launches the applications. Install this first — it is the only thing that activates a computer.

    Required for a membership. Its bootstrap installer is built and waits for code signing; until then there is nothing to link.
