How do I have to install the Catia V5 Add in (Student Package) ?

Hello, I have bought a student package and I wanted to ask how I have to install the Catia V5 Add-in so I can use it on my desktop? Or what apps I have to install to use it. Every time I want to start the Catia Add-in the following message pops up. I want to start the application on the left on the picture.

Thank you
