Why can't I open things with Catia V5 anymore?

I used to have the option to do so but now it doesn't show up, any reason why?


i have installed the relevant connector, but it just does not show up.



also when opening the "CATIA V5 Add-in - 3DEXPERIENCE R2024x" on my desktop, Catia used to open with a load of 3dExp options but now its doesn't have those...
