As a license administrator,
you can prevent any installed version of SmartDraw for Windows from loading files from or saving files online.
You can also prevent users from accessing SmartDraw's online edition completely.
If you want users to be able to work on diagrams using the online edition, but you don't want them to be able to share them by embedding them
on public blogs or emailing them to users outside of the site license, you can turn off just the sharing feature of SmartDraw.
