Does not add to Context Menu

[mwidunn]

I go into Settings and select "Add 'Convert to XnConvert' to context menu." However, nothing appears in the context menu.
I have tried opening XnConvert with Administrator privileges and, then, selecting the option. No difference: It does not appear
Computer has been re-started since selection. Still, it is not appearing in the Context Menu.
