Apols if this turns up twice but I just got to the end of typing, used a button on my mouse (that should be set up to paste) and lost the lot! Frustrating or what!

OK - I did a Restore to a point the day before the Photoshop updates were released. The Restore point told me that only Photoshop and Lightroom would be affected.

After the Restore Lightroom was indeed at the earlier version but strangely, Photoshop wasn't.

However - the "Save to PDF" in Word & Excel were now working.

I Uninstalled Photoshop, and then reinstalled it and the latest version of Lightroom.

"Save to PDF" continued to work.

There are no Windows updates needed - that's all up to date.

So I have no idea what was causing the problem but at least it's now working and I can get on with things! Something corrupted I guess.

Many thanks for your help.
