Using Extenstion from eclipse not working

I’ve download the Toad extension from the eclipse marketplace in eclipse neon3, I restated eclipse and open new perspective and I don’t see it…
try to also install it from local but it doesn’t give you the option since its already installed, any idea how can I use it ?

I tried even to remove it and install it again (from local and not from the marketplace and it is not showen in the prespective pop-up…)

This is the extension
