Hi Martin, I am getting this too. Specifically I loaded 2 profiles and after reboot I get the following I am using Windows 10 version 1703 (OS Build 15063.332), with all updates. I think I figured it out though. I found the xml files and put them in the same directory of the monitorswitcher.exe and it seems to work. I did switch over to command line vs the gui. more specifically I made some .bat files that switched to where I have the .exe and I made shortcuts, with the hotkeys to run the bat files....
