# Windows installer

NSIS script: `installer.nsi`. Output: `build/relspec-setup-windows-amd64.exe`.

## Build

```
make installer-windows
```

Needs `makensis` (package `nsis`). CI builds and uploads it on release.

## Installer

- Installs `relspec.exe` to `%ProgramFiles%\RelSpec` (admin).
- Adds the install dir to the system `PATH`; removed on uninstall.
- Registers in Add/Remove Programs.

## Update check

```
relspec update            # check, prompt, download + run installer (Windows)
relspec update --check    # report only
relspec update --yes      # no prompt
```
