In Delphi XE3, I have been using remote control of Microsoft Word via TWordApplication, e.g. for assembling quotations from multiple documents; it mostly worked fine, even though it sometimes hanged and needed a restart of my program. Now it suddenly stopped working: when I call WordApplication.Connect (the first step), in unit WordXP, line 30576 (procedure TWordApplication.Connect) it always raises an exception "Interface not supported" in the line containing: Fintf:= punk as _Application;
It seems it can no longer establish the interface with Word.
In Delphi, Components | Install packages, I find that (as usual) "Microsoft Office XP Samples Automation Server Wrapper Components" are enabled, but not the similar stuff for Office 2000. It had always worked like that.
I migrated from Office 2013 to Office 365 a couple of weeks ago. Remote control of Word continued working, only now it stopped. I wonder whether an update of " Microsoft Office Click to Run" might have broken it.
I tried several things without success: starting the Office 365 installer again, and Start menu | Apps and Features, searching for Office, making a " quick repair" for various items.
It seems that Office is broken, not my program - right? Any ideas how to fix it?
