#
# darktable ships as an Inno Setup installer (NOT NSIS, despite winget's
# metadata reporting "nullsoft"). Inno ignores the NSIS "/S" switch and launches
# its GUI wizard, so we pass Inno's silent switches instead.
#
# darktable's installer has a postinstall [Run] entry that opens the online user
# manual via shellexec/runasoriginaluser and is NOT flagged "skipifsilent", so it
# fires even under /VERYSILENT. On a headless host that step never returns,
# leaving the Setup process alive indefinitely and holding the installer-file
# lock -- a plain "Start-Process -Wait" would block until killed even though the
# files install correctly. So we launch Setup, poll until darktable is registered
# in Programs and Features, then stop the lingering process to release the lock.
#
# The installer defaults to PrivilegesRequired=admin, so it installs machine-wide
# when run elevated. "/ALLUSERS" is intentionally omitted: darktable's installer
# sets PrivilegesRequiredOverridesAllowed=dialog (not "commandline"), so the
# command-line override is not accepted and the admin default already covers all
# users.
