SW2GZ.iss

; SW2GZ installer — auto-removes previous install, kills SolidWorks if running,
; deploys + registers in one click.
; Build: ISCC.exe /DMyAppVersion=<version> installer\SW2GZ.iss (see BUILD.md)
#define MyAppName        "SW2GZ"
; MyAppVersion drives AppVersion + the output filename. Pass it explicitly at
; build time so it tracks the git tag being released, e.g.:
;   ISCC.exe /DMyAppVersion=2.8.0 installer\SW2GZ.iss
; (BUILD.md and .github/workflows/release.yml derive this from `git describe
; --tags`.) The fallback below is only for ad-hoc local builds without /D —
; bump it when it drifts too far behind the latest tag.
