How to install SAP Logon Transfer on Windows

SAP Logon Transfer is a portable Windows app — there is nothing to install. You can either download the ready-made .exe and run it, or build it yourself from the Python source. This guide covers both.

Option 1 — Run the downloaded app

1. Go to the download page and save the .exe.
2. Double-click it. No installer runs; the window opens directly.
3. On first launch Windows may show a SmartScreen notice because the app is new and unsigned. Choose More info → Run anyway. If your organisation blocks unsigned apps, use Option 2 to build it in-house.

The app only reads and writes your SAP Logon configuration files. It does not touch the network, the registry, or any password store.

Option 2 — Build the .exe yourself

Building from source means you run exactly the code you can read. You need a Windows machine with Python 3.9+ installed (tick “Add Python to PATH” during setup).

1. Install the build tools

pip install pyinstaller PySide6 openpyxl

2. Build a single portable .exe

From the folder containing the source files, run:

pyinstaller --onefile --windowed \
  --name "SAP Logon Transfer" --icon=app.ico \
  sap_logon_transfer_qt.py

Keep sapconfig.py, i18n.py, cloud.py and report.py in the same folder — PyInstaller bundles them automatically.

3. Find your app

The finished app is at dist\SAP Logon Transfer.exe. Copy it anywhere.

Smaller or faster builds

Two ready-made scripts ship with the source. build_small.bat excludes Qt modules the tool never uses to shrink the file; build_onedir.bat produces a folder that starts instantly instead of unpacking on each launch. Both build inside a clean virtual environment so no stray libraries get bundled.

First run

Click Auto-detect and the tool finds your SAP Logon config at %APPDATA%\SAP\Common\SAPUILandscape.xml. From there you can export folders, import onto another machine, back up to your cloud folder, or export a report. See what that file contains if you're curious about the format.
