  6. If you have McAfee AV installed, uninstall it!
  7. Reinstall only JMRI version 4.26 and the most recent version of Java 8.

NCE recommends using only JMRI version 4.26 and the most recent version of Java 8. Java- JMRI- FAQ - Windows 10 and 11 have built-in support for the Ch340 chipset driver. Do not install any other driver unless instructed to do so by NCE. If you need to do a manual installation for older USB boards with the CP210x chipset, go here for the driver:

All versions of the USB interface work with Windows 11. The issue is that Windows blocks driver installation.  The location to allow the driver to install is now buried further in the update section.
 Look in The Windows Advanced update section in Settings > Update & Security > Windows Update > Advanced options. 



A more detailed description of this process is in the attached zip file


Manual driver installation is not needed for Windows 11
Remove ALL the jumpers off the USB board. They are not needed.
Look in Windows update AND the Windows optional update section. Install everything in BOTH sections. Keep rebooting as required and checking these sections until they're both empty and up to date.
 If you cannot resolve it, I can remote access your PC and check everything.
