AppMint Installer

AppMint Installer is the official setup tool for AppMint, sibling of Dex Installer's Inno Setup but dedicated to the Mint suite. Fully offline Windows bundle: ships with Node.js 20 LTS (silent MSI), Python 3.12 (silent EXE, optional for the sidecar), NSSM for Windows service management, and all AppMint `node_modules` pre-installed with `npm install --omit=dev`. The final setup.exe is self-sufficient — installs AppMint even on a freshly formatted server with no internet connection.

The wizard exposes 6 custom pages (in addition to Inno Setup's standard Welcome / License / Ready / Finish):

1. **Prerequisites** — info about target requirements (Windows 10/11 or Server 2019+).

2. **Folders** — `ADMIN_DB_DIR` (admin DB + sessions + .secret-key), `LOGS_ROOT`, `SCRIPTS_ROOT`. Default: under `%PROGRAMDATA%\AppMint`, outside the code folder so re-deploying does not lose data.

3. **Ports** — HTTP port (default 3100) + optional native HTTPS with cert/key path.

4. **Windows service** — NSSM service name, auto-start at boot, choice between `NODE_ENV=development` or `production`.

5. **Features** — Python sidecar toggle (for server-side Form Builder rules), log retention, default language IT/EN, KB embeddings (Ollama / OpenAI / disabled).

6. **Install log** — live real-time output of `npm install`, `npm run init-db`, NSSM registration and service start.

After the wizard, post-install execution does: silent Node MSI install if missing; silent Python EXE install if sidecar enabled and Python absent; `generate-env.ps1` reads the collected config and produces a complete `.env` with random `SESSION_SECRET`; `deploy.ps1` runs `npm install` (idempotent: skipped if `node_modules` are already in staging), then `npm run init-db` (creates admin schema + `admin/admin` user with `must_change_password=1`), then calls `deploy-service.bat` with `/skipenv /skipinstall /skipinitdb /yes` flags to register the Windows service. Starts the service if requested and opens `http://localhost:<port>` in the default browser.

**Uninstall** from Control Panel (or `uninst000.exe`) invokes `undeploy.ps1` which stops and removes the NSSM service via `undeploy-service.bat`, then Inno Setup deletes the `{app}\` folder with the code. **Does NOT touch** `ADMIN_DB_DIR` or `LOGS_ROOT`: data remains for backups or future reinstalls (you can delete them manually if you really want a full reset).

Idempotent: re-running setup.exe over an existing install pre-populates the wizard with choices from the current `.env` and only re-deploys what changed. Building the installer requires Inno Setup 6 + Node 18+ in PATH and runs via `Build-Installer.ps1`, which copies AppMint sources to staging, runs `npm install --omit=dev`, and produces `dist\AppMint-Setup-X.Y.Z.exe` (~150-300 MB).
