; Replaces electron-builder's "is the app running?" check (customCheckAppRunning). Runs at the start of
; installing, BEFORE the old version is removed and before any file is copied.
;
; The stock check only looks for "Bible App.exe". But the app also starts programs from its own folder
; - the local AI server (llama-server.exe), speech (whisper), the upscaler - and if the app is closed
; hard, those are left running. They hold their files open, so copying the new version fails and the
; installer says "Bible App cannot be closed. Please close it manually and click Retry" even though
; the app is plainly closed, and Retry can never succeed. So:
;   1. ask the app to close (it then stops the AI server itself), and give it a moment;
;   2. force-close anything named Bible App.exe that is still there;
;   3. force-close the app's own helper programs by name (plain taskkill, nothing to go wrong);
;   4. as a backstop, force-close EVERY program running from this install folder, whatever its name.
; Step 4 matches by folder, via WMI (works from this 32-bit installer on 64-bit Windows, where a
; 32-bit process cannot read a 64-bit process's path). The folder travels in an environment variable
; so a quote or space in it can never break the command, and it refuses to act on a bare drive.
; No question is asked first: installing this version replaces the app, which is what was asked for.

; Versions 1.4.35 - 1.4.37 were built on macOS before build/installerIcon.ico existed, and their
; uninstallers are damaged: they fail NSIS's own integrity check ("Installer integrity check has
; failed"). electron-builder rebuilds the uninstaller in JavaScript on macOS and leaves out NSIS's
; icon patch, so whenever the installer and uninstaller icons differ (NSIS's two defaults do), the
; checksum is wrong. An update runs the PREVIOUS version's uninstaller first, so those versions could
; never be updated: the damaged uninstaller fails, and the installer reports "Bible App cannot be
; closed" (it also cannot be uninstalled from Windows Settings).
;
; For exactly those versions, the old uninstaller is not run: its UninstallString is cleared, so
; electron-builder's uninstallOldVersion finds nothing to run, and the new files are copied over the
; old ones. This installer then writes a fresh, valid uninstaller and registry entry. Every other
; version still goes through the normal uninstall-then-install path.
