The Sims 2 University Update

[kre]

When I (my daughter of course) start The Sims University, for a short time the University logo pops up and then the (main game) Sims 2 logo loads and its movie starts.
In the Main menue I only can choose between the 3 (main game) neighbourhoods (Merkwürdighausen etc. in German), the University neighbourhoods are nowhere to be seen.
Seems there's nothing different from the main game.
Is that correct? Or did we fail in any way?
As University overwrites or deletes Sims 2-savegames we have installed maingame and addon on my own PC first to test and have a look at it before she does it on her PC.
University will be launched with the Sims2EP1.exe, Sims 2 with Sims2.exe and both games are NOT installed in the same folder. It was also version-updated while installation.
I personally have no knowledge of/interest in playing Sims-games, but my daughter asks:
Can anyone tell me what's wrong? Or isn't it?
