Some older digital systems (Märklin 6021/51 or Intellibox classic/IR) are connected to the computer by means of a serial port (RS232). Depending on the size of the layout a higher resolution is recommended. The minimal screen resolution to run iTrain properly is 1280 x 800. The minimum amount of required memory is 1 Gb of RAM. You will need at least a computer with a 32-bit or 64-bit operating system like macOS, Windows or Linux. There are some requirements to be able to run this program. Older project files should first be opened and saved in iTrain 4.1 before opening them in iTrain 5.x. After installing version 5.x you first have to enter the new license key for version 5 before you open the project file that you used in 4.1.

That means that people who have bought a 4.x license have to buy an upgrade to be able to switch. It is recommended to always check the forum announcements before installing a new upgrade. These steps are described in the announcements on the iTrain forum. Without these steps your current project will not behave correctly. When moving to version 5 a few manual steps are necessary. It is recommended to read the following to ensure proper installation. The downloads can be found on the right side.
