Re: My sims 3 launcher won't download sims3packs (Mac)

@krist9769  Sorry for the late reply; I've been otherwise occupied for a few days and fell way behind.  I did however download your sim, at least one copy of the three you linked, with no issues whatsoever.  I initially saw the same error you did, but when I clicked OK, the sim started to install.  I tested in two different clean Sims 3 folders.

Please try repairing the game in Origin: open your game library, right-click on the Sims 3 icon, and select Repair.  Even if you've already done so, the new patch today changed a bit about what the repair does, so it's worth doing again.  Then try to download your sim.  If you can't, I can send you the relevant files, although I'm not totally sure they'll work, and you might be missing a bit of content since I don't own Katy Perry.  But maybe it's better than nothing.
