Install applications and models through the launcher

Short answer: Open the launcher, choose an application, choose Install. Applications and the models some of them need arrive as signed packages that the launcher verifies before installing.

Steps, at launch

1. Open the Litesum Launcher and make sure the computer is activated.
2. Each application card shows its status. Choose Install on the ones you want.
3. The launcher downloads the package, checks its signature and its SHA-256 against the signed catalogue, and installs it into your user folder.

Models

Enhance ships its AI models inside its installer, so nothing is downloaded afterwards. Where an application needs a model later, the launcher fetches it through the same verified path and says so before it starts.

Where things go

Everything installs into your own user folder. No administrator permission is asked for. Uninstall from Settings ▸ Apps as with any other program; your images and documents are never touched.
