Why can't I see InDesign CC in my Extension Manager CC

Hi everybody,

I recently installed InDesign CC, and I wish to install an extension with the Extension Manager. I encounter the following problem:

As you can see on this screenshot, my InDesign CC is running, and so is my Extension manager CC. But in my Adobe product listavailable in Extension Manager, all we can see is "Others" (in the left, "Autres). But I cannot see InDesign.

My underlying problem is I cannot install an extension with a zxp. The extension is installed and I can open the panel in InDesign, but it is empty. I assume this problem with Extension Manager is responsible for it.

I'm working on a Mac OS 10.6.8 and an InDesign CC 9.2

Thanks
