Software version and Windows compatibility are critical. As a general rule, earlier versions are not supported on newer operating systems. For instance, version 5.20 was the minimum required for Windows XP. While version 8.40 (CPR 9) and later can work on Windows 7 64-bit, it is not guaranteed to be reliable. For maximum reliability with version 8.10.00, Windows 7 32-bit or a well-configured virtual machine is your safest bet.
Because the activation is tied to this specific disk, it is paramount to create a backup of this disk immediately and keep the original safe. If the disk is lost or corrupted, recovering the license can be a difficult process with Rockwell support.
CPR9 was designed for Windows XP and Windows 7. While it can run on Windows 10 using "Compatibility Mode," it is much more stable inside a Virtual Machine (VM).
