I've seen others asking similar questions but not the same. Please note I am talking about Sims 3 Store content and not mods. Nothing third-party has any issues running in my game, though I've removed it all thinking that would help and it did not. I'm playing on a PC, using the EA app (not Origin) and opening/installing using the sims 3 launcher. 

Game Version: 1.69.43.024017

I am launching it using the EA app not Origin. When I try to use Origin it tells me to update to the EA app. I did not try to download 1.69, I just realized the other day the version was different. I used 1.67 up until a month or so ago. Not sure when it updated, but now I can't download any store content. The error message says: Installation failed: Please make sure your game has the latest Software Updates and try again. I don't know what to do. I'm not sure if it's the store content that isn't compatible or if its the launcher or what is going on. But there's so much missing from my game it's hard to play. I have already tried uninstalling and reinstalling the Sims. Please let me know if anyone has found a solution to this issue so I can play my game, thanks.
