Legacy Interceptor ECU software for a computer with Windows XP and a 9 pin serial port.
This is a single file .EXE, not a full installation. Unzip and paste the file to the desktop.
For Windows 7 and 10, if there are any problems, right click on the icon and select "Troubleshoot compatibility" .
If a USB to serial converter is used, ensure its driver software is installed and the com port number is set between 1 and 4. This can be checked in Windows Device Manager. Set the Interceptor software com port to the same number.
