Toolbar and ribbon bar DO NOT EXIST!

Hi
I have newly started to learn CATIA V5 2017 P3 and my UI is not the same as it should be.
The vertical icons in the right are not attached and they are free to drag them
I'm an apprentice so I need ur help to tell me what can I do to fix this
TNX A LOT
As u see in the following picture I have no ribbon bar or toolbar as I should have
