Means as much as: do start Adobe Acrobat DC before continuing an confirm the enduser license agreement.
What do I hav to do. DC is installed and running.

What happens if you save the file locally and then double-click it?
If this is happening with a new installation, you need to start Acrobat as a standalone application first, before you can use it's browser plug-in. This is what this error message is trying to tell you.
If you have both Adobe Acrobat and the free Adobe Reader installed, make sure that you start both (and potentially accept the EULA) before you use the browser plug-in.
In general, make sure that you follow the instructions on this page to enable Acrobat/Reader in Safari: Display PDF in browser Adobe Acrobat DC, Acrobat Reader DC
If after the previous steps, you still have the problem, take a look at this old question: End User License Agreement
Look for "Test Screen Name"'s comments and instructions to remove the plug-in files.
