Update. I discovered that Word documents would, in time, open (about 2.5 minutes). I decided to look for another program to examine my registry for errors that perhaps Easy Cleaner was missing. Turned out it was missing a lot. Used Glarysoft Registry Repair and found a TON of errors in the registry. Repaired them and all Word, Excel and Outlook hyperlinks are working beautifully. I have no idea how the registry got so messed up on an almost brand-new reformatted install, but hopefully now all will stay fixed.
