AcroCEF errors in Win10 64bit

I have seen many posts on the AcroCEF error but none have helped me to solve my errors.   I have the very latest version of Adobe Acrobat Pro in Windows 10, kept up to date by Adobe Creative Cloud.  I have used this Acrobat for years with no issues. The very latest Acrobat Pro update with all the menus changed around, now pops up an error dialog box  "AcroDEF.exe Installation Error", over and over 3 to 5 times before I can start to use my Acrobat.   I have tried the  "Repair Installation" in the Help menu, but it did not fix the problem. This is VERY annoying, and is forcing me to keep Acrobat Pro open all the time so I don't have to deal with the bong, error, bong, error, bong error etc, etc.   Any magic fix for this?  Thanks
