Sims3Packs pretend to be installed.

[Burakotka]

What I mean by the title is that I have downloaded a multiple sims3pack files and put them in the right directory and stuff, and they appear in the launcher, everything is nice and neat. I install them, they are ok, seem working. I play the game, they're not in. I get back to the Launcher and... They show as they are not yet installed.
I tried deleting and putting them in again, trying all the different weird ways and they just don't want to work.
Please kindly help?

I think I figured it out in some way - I converted the sim3pack into packages.
It's not the best way to solve this, cause it makes the game so terribly slow (it actually took 1,5 hour for game to load, and it was just to try if it works...)... I couldn't come up with anything better.
