CEP installation does not create a folder in Program Files. UC

How is it definitely installed? I always used the installer and manually copied the CEP folder from Documents to C:\Program Files (x86)\The Sims 2 Starter Pack\Fun with Pets\SP9\TSData\Res\Catalog. Is that correct?

So I ended up with two: the one the program installed in Documents and the copy I made to Program Files. From what I’ve seen, the installation on the UC is different, and I’m not sure if I’ve always used it correctly.
