Keyman Developer: "Test keyboard" command behaves oddly

If I create a new keyboard an add some code, if I try to test my keyboard with “Test keyboard” in the keyboard menu, I get an error message that Keyman Developer was not properly installed (code 0x00000). If I start the debugger, that works and I can test my keyboard. And once I have started the debugger, Test Keyboard will work on that keyboard from then on.

Once testing this I got a dialog that Keyman Developer had a problem and needed to close. It could not submit the report because Windows defender reported a virus in the temp file.
I’ve attached the tsi it could not submit. tkd6607.tsi (290.1 KB)

I have Keyman Developer and Keyman Desktop

Hi Steve,

I think we’ve addressed the Test Keyboard issue with Keyman Developer 14 / Keyman 14 beta. Would you be willing to try with the beta version downloadable at

I tried 14 beta (14.0.235) and I still get a confusing error message instead of a prompt to compile the keyboard when I enter some rules in a new keyboard file and save it.


I’m not sure what is going on here – it sounds like we may have to do some deeper debugging to trace the cause.

  • If you use F5 to run the debug mode, does that always work?
  • Is Keyman running before you start Keyman Developer?
  • As well as answering those questions, can you also capture an debug log which may provide more detail please?

Do you still experience this issue in the latest stable version of Keyman?
