I have the latest version of Keyman (10.0.1113.0). When I install keyboards in Keyman desktop, they are listed as associated with a language. But when I go to settings > Time and Language > Region and language, find the language associated with a Keyman keyboard and click Options, it does not list the keyboard, it says “unavailable input method.” I cannot add a Keyman keyboard as an option to another language in Windows settings, because it does not show the Keyman keyboards in the list of keyboards the way earlier versions of Windows did. I can use the Windows language bar to switch to my Keyman keyboards. What I am unable to do is set up automatic keyboard switching in Toolbox, Toolbox doesn’t show the Keyman keyboards in the list of installed keyboards.
My Windows 10 version: 1803 Home.
