I ran into the same problem trying to use the KHTMLPart-based widget instead of QTextBrowser-based widget:
"The program on your computer which provides access to the ms-its protocol could not be started. This is usually due to technical reasons."
If https://bugs.launchpad.net/ubuntu/+source/kchmviewer/+bug/252159/comments/11 is true, why okular doesn't seem to have any chm support?
