Re: Sims 3 Store Content Will Not Install on New EA App
@hannashaven Did you also try installing the store content into a clean user folder, as described in the last post in that locked thread? If not, that's the next step.
If that doesn't or didn't help, the next step is to try downloading with a different browser than your usual one, for example Firefox works well with the store. Please use another clean folder for this test, just to be thorough.
