installer.iss

; Inno Setup script for ModbusLens.
; Packages the --onedir PyInstaller build (dist\ModbusLens\) into a normal Windows
; installer -- no runtime self-extraction, so it avoids the whole class of onefile
; bootloader bugs (non-ASCII usernames, AV races) documented in notes.md, and reads as
; a normal app install to AV heuristics instead of a suspicious single self-extracting
; exe.
;
; Build first: python build_exe.py onedir
; Then compile: "C:\Users\PlayGround\AppData\Local\Programs\Inno Setup 6\ISCC.exe" installer.iss

; Same AppId across versions is what makes a newer Setup.exe recognized as an update to
; an existing install (same install path, one Apps & Features entry, not a duplicate) --
; never regenerate this GUID for ModbusLens.

; Update-safety: if ModbusLens.exe is running when the user installs an update, Windows
; would otherwise lock the file and the install would fail outright. CloseApplications
; detects that (via Windows' Restart Manager) and prompts to close it first;
; RestartApplications reopens it afterward.
