"Acrobat failed to send a DDE command".

Suddenly I get this message when I try to start Acrobat, either
directly or from a file.

Is there any fix? Peter

Thanks. Before trying all the fixes, I did a 2 week-old system
restore and this fixed it. I'll have to reinstall some small
programs and I'll watch them carefully.

God bless System Restore!

I've never understood the affection for a mechanism that makes unannounced
changes to a PC.
Do you mean System Restore?

Yes, of course. System Restore is a case where the cure is worse than the
disease. It's one of the very first things I disable on each new PC, along
with UAC and a few other things.
