# Bag3 Windows exe build (run all commands in this python/ folder) py -m pip install --upgrade pyinstaller py -m pip install --upgrade pywin32 py -m pip install --upgrade Pillow "qrcode[pil]" requests py -m PyInstaller --noconfirm --clean Bag3.spec # Output: dist\Bag3\Bag3.exe plus dist\Bag3\_internal\... # Copy the ENTIRE dist\Bag3\ folder to the client PC (not only Bag3.exe). # --- If the client exe flashes and closes --- 1) On the client PC, open cmd in the Bag3 folder and run: Bag3.exe You should see the error in the console, or open bag3_startup_error.log next to Bag3.exe. 2) Compare BUILD machines (both should match): py --version py -m PyInstaller --version py -m pip show pyinstaller pywin32 Pillow qrcode requests A broken build is often caused by: - Different Python major version (e.g. 3.13 vs 3.11) - Incomplete tkinter on that Python (Store Python / partial install) - Old PyInstaller missing Tcl/Tk files in the bundle 3) Rebuild on the machine that works, or reinstall Python from python.org (64-bit) and reinstall deps above, then rebuild. 4) Bag3.spec disables UPX (upx=False) for stability; do not re-enable unless you test on the client. 5) Client needs 64-bit Windows and Microsoft VC++ Redistributable (same as your Python installer). 6) Antivirus may quarantine files under _internal\ — whitelist the Bag3 folder if the log mentions missing DLL.
