Dear
I gave this first a try as it's the easist to start with.
I don't have the installation diagnostics , I do see to uninstall the installation, and other things, like status monitor.
But I anyway went to step 2 and followed from there all steps.
after reboot, I started Cotnrol center 4, icon appears in the right bottom of my screen, but the windows does not appear on screen, it's as beforre: if the scanner is available in printers and scanners, Control center refuge to start.
If I remove the scanner from device manager, and shut down Control center4 in task management, and start the app again, then the app opens completely but there is no scanner so it can not find it.
And crazy: before I tried this, i again uninstalled everything using the uninstall option in brother utilities, rebooted, installed again the full software, then I do see a device scanner in device manager but the printers and scanners window is empty. Controle center 4 opens but gives the message no device found.. blabla same error code as you mentioned.
