The official PA Soft website no longer offers free downloads. Many forums (Bimmerfest, E46Fanatics, Bimmerforums) host user-uploaded versions. However, exercise caution – malware-ridden copies exist.

The Installation Ritual for Windows 10

To actually be "top" (i.e., functional), you must follow this specific workflow: In Device Manager, find Ports (COM & LPT)

Disable Driver Signature Enforcement: Restart your PC while holding Shift. Go to Troubleshoot > Advanced Options > Startup Settings > Restart > Press 7 (Disable driver signature enforcement). This is mandatory.
Plug in the Scanner: You need the physical hardware (a red 20-pin to OBD2 cable with a switch). You cannot run this software without the cable; the software is just a frontend.
Force the Driver: Open Device Manager. Find the unknown device. Manually point it to the FTDI folder in your download.
Set Compatibility: Right-click BMWScanner_v1.4.0.exe > Properties > Compatibility > Run this program as administrator > Windows 7 mode.
COM Port Setting: In Device Manager, set the COM port to COM 1 (The software is very picky; it hates COM 4 or higher).

Phase 6: Test Connection (on car)

Connect scanner to car’s OBD2 or 20-pin port (under hood for E36/E38/E39).
Turn ignition to ON (KOEO – key on, engine off) – do not start.
In software, click Connect.
You should see VIN, model, and module list.

If successful – congratulations. You now have the top BMW Scanner 1.4.0 running on Windows 10.
