Objects unusable because they require a unavailable extensions

Hello everyone! I need help with using extensions.
I have got the newest version of fusion that I know of (Attachment 26469) and I am very happy with the quality of the product. However, when I attempt to update or install some extensions, this shows up. (Attachment 26471)

Please help!

This message just means that you don't need to install these extensions, they are provided with Fusion and are updated by the Fusion update patches.

OK, thanks!
