Problem with Swiffy - not seen in Flash IDE's menu even though installed

programming flash

In Flash CS6 I installed Swiffy.

I can see it in ‘Adobe Extension Manager CS6’, it is enabled.

BUT in the Flash IDE, in ‘Commands’ menu, I see no menu item ‘Export as HTML5 (Swiffy)’.

As It’s supposed to.

What can I do?
