When publishing to a word document, the final document only has the first page

I had the same problem and now i've got it solved!!

It is because we don't have Microsoft Word. Or it's because we have other similar text-editing software which intervenes the communication between Storyline and MS Word.

First:
I failed export word file on these PCs:
PC 1 with only WPS Office (which is similar to MS word) for text and article editing;
PC 2 with both WPS Office AND Microsoft Word
PC 3 without WPS Office nor Microsoft Word

Then:
I successfully exported word file on these PCs:
PC 3 with only Microsoft Word installed
PC 2 just with WPS uninistalled and left only with MS Word

And I failed again on this PC:
PC 3 with MS Word and just with WPS installed

SO it's obvious! You can see what happens to PC 1, 2, and 3.

Good luck to you all!
