Dear Rick! I think I do have the index file . I suspect it got corrupted or something. Actually I want to post here a screenshot which you could check and advise me on what could be done.

Here what I get when I open index.xml file.

Is there any way to correct something?

Thank you so much for your help.

Make sure you have an Index topic in your help file. Help Builder requires a root Index topic. Most likely you deleted it by accident.

When I'm building a Help file and running "Build HTML Help file" option from Tools menu, as a result I get the following message on the "Help compiler results" screen;

"Help file not built!"

The Help File was not built
....
Topic not found

Would you be knowing the reason for that? Before I used to compile without running into this problem.

Thank you for your help in advance.
