I should have explained that the updated version would be built
overnight in Chicago, so pe rhaps you got yesterday's version?
Today I see this entry for  http:/denemo.org/~jjbenham/mxe

do you have the 8th July version?

Even with yesterday's version there is a simple test:
create a file named junk.mid and then invoke the Export->Export MIDI
command and choose to save to this same file. You should get a warning
popping up asking if you want to over-write the already existing file.

If you change the permissions on junk.mid to prevent over-writing then
you should get a further message saying the save to junk.mid failed,
but only with today's version.

One other test you can do is to try the command

Command: Playback View
Displays the music fully typeset on one long page (the Playback View).
Click on a note to play from there or drag to loop play.
Location: Main Menu ▶ Playback
Internal Name: PlaybackView

this will invoke LilyPond to generate the MIDI rendering, which is more
sophisticated than Denemo's in-built MIDI generator. Does that work on
your machine (what version of Windows do you have?)

That will be a false positive - as it happens the file
generate_source.exe is not actually needed - you can delete it without
any problem. There are unfortunately hundreds of executable files in
the bin directory which make it highly possible that a simple search
for a suspicious sequence of bytes will throw up a match.

Thank you for testing!
