# Installer (Inno Setup 6). Recipes run under MSYS2 bash, so fallback paths
# are POSIX-style and quoted. Checked in order: PATH, the winget per-user
# location, then the classic machine-wide "Program Files (x86)" location.
# The per-user dir is resolved with `cygpath -F 28` (CSIDL_LOCAL_APPDATA,
# via the Windows API) because recipe environments here scrub Windows env
# vars like LOCALAPPDATA — the same phenomenon as TMP/TEMP at the top of
# this file. Both candidates are overridable (used by the error-path test).
# MSYS2_ARG_CONV_EXCL="/D" stops the MSYS runtime from rewriting the
# /DAppVersion switch into a Windows path (which ISCC would then reject as
# a second script filename).
