Save as PDF

Many thanks tlnet.  Sorry, yes WP X5.   Build is 15.0.0.528, a number that suggests it is later than the 15.0.0.512 you quote. I had already tried a"Repair" but repeated it today. No improvement.

Windows is 10 Home:  version 1803, Build: 17134.345

I have, however, found an easy way round the problem.            With the document open in the WP window, click on "Print" and change the printer to "Microsoft Print to PDF". A dialogue box opens and you save the file in in PDF format.

Would still be interested to know how to solve the WP error tho.

Does this occur even with a simple file, such as one with just the word Hello in it?

Thanks christian_h. I have had a quick read through but will go back for a closer study.
