## Reasonix per-user NSIS installer.
##
## This file is COMMITTED and customized (Wails leaves an existing project.nsi
## untouched and only regenerates wails_tools.nsh). The customizations vs.
## Wails' default template:
##
##   1. REQUEST_EXECUTION_LEVEL "user" + InstallDir under $LOCALAPPDATA - install
##      without administrator rights. This is what lets the auto-updater re-run a
##      freshly downloaded installer silently (`/S`) with no UAC prompt.
##   2. Uninstall registry under HKCU (not HKLM). Wails' wails.writeUninstaller /
##      wails.deleteUninstaller macros hard-code HKLM, which a non-admin install
##      cannot write - so we inline HKCU versions below instead.
##   3. InstallDir is remembered across updates via InstallDirRegKey +
##      InstallLocation (HKCU\...\Uninstall\InstallLocation). When upgrading from
##      a build that did not write InstallLocation yet, .onInit falls back to the
##      old DisplayIcon path before using the default. Without this, every release
##      forces the user back to %LOCALAPPDATA%\Programs\Reasonix even if they had
##      moved the install to a different drive (e.g. D:\Tools\Reasonix); the silent
##      auto-updater would re-run with /S into the wrong dir, leaving the old
##      install orphaned.
##
## Everything else mirrors Wails' generated default. Defines below override the
## ProjectInfo values that wails_tools.nsh would otherwise populate.
####

## Install per-user (no admin). Must be defined BEFORE including wails_tools.nsh,
## which only sets the "admin" default when REQUEST_EXECUTION_LEVEL is undefined.
!define REQUEST_EXECUTION_LEVEL "user"

## Include the wails tools (auto-generated; provides INFO_* defines and the
## wails.* macros used below).
