Can't install/use CATIA V5

Here I am again...

I have subscribed to "3DEXPERIENCE CATIA for Students", and granted myself the role to use CATIA V5 in the Platform Management dashboard.

Then I installed the 3DEXPERIENCE Launcher and the apps, choosing to "Install All Granted Roles". Installation completed without errors. Now I can use apps like Part Design, but if I try to launch CATIA V5 (through My Apps or the desktop shortcut), it just won't work.

The "CATIA V5 launcher from 3DDrive" pops up, with the error "Unable to retrieve Catia V5 Application. Please, verify CATIA V5 is correctly installed."

I checked the folder where the desktop shortcut points, and effectively CATIA is not there.

The problem is: how can I solve this and install correctly CATIA? I have laready tried to reinstall everything and no result
