Adobe Acrobat Reader DC

After finally upgrading my computer from Win7 to Win10 the Adobe Reader program opens one file and then will not open any others or create pdf files.  The program just does nothing when I click to use.

The solution is to disable Protected Mode.  First, make sure you can open Reader DC.  If you cannot, then open the Task Manager by typing Taskmgr in the search box near the Start button.  Close all instances of Adobe Reader.  Open the program, not a file.  Click on Edit, Preferences.  Go to Security (Enhanced) and uncheck the box to enable Protected Mode at startup.  Click Ok.  Try using the program again.
