Can't produce a .chm from a .book file
Hi, I am unable to produce a .chm from a .book file. I can make a .chm from each individual chapter (except the auto-created files, of course). I can create a .chm from other, similair, .book files. I recreated the .book file and added the existing files to it, but it still will not produce the .chm file. I can produce pdf and Responsive HTML5 files from the .book file In each case, I've used the same settings file and the same .css.
I have looked at the log file that is produced, in each case, it says it compiled normally. I deleted the temp files, which produced no change.
I am on 2019, 15.0.8.979.
It seems to fail at the "Generating HTML Help system" step. I get an error: "An internal error has occurred. This program will now close.".
Any suggestions?
