Did you copy and paste the error message or hand type it?
My directory tree is
C: -> ProgramFiles(x86)-HTML-Kit->Tools->bin
and there is no file Embedding in that directory.
And no error message when I start.
I tyoed it in, could not copy and paste at the time.
The odd thing is that the error message has not happened since. However, I don;t know what no file -Embedding in directory means,
