sims 3 store content: I "do not own the item"

@rinandia  When you see this error, does it help to simply refresh the browser page?  You can try downloading from the items' individual product pages rather than your purchase history so you're not refreshing the entire history.

If that doesn't help, try using a different browser.

If that doesn't help either, please list at least a few of the items that won't download properly.

I have tried refreshing the browser. I had a few successes by looking at the product pages, but most of my items are still not downloading. I have tried three different browsers now (Chrome, MS Edge, and Firefox). 

Many items will not download, including...

Worlds, such as Aurora Skies (gold edition)

CAS Sets, such as Luxury Resort Attire

Build Sets, such as Full Ultra Lounge Set

CAS items, such as Short and Choppy (an AF hair)

Build items, such as Cellar Arch

Lots, such as Olympian Physique

Compilations, such as March 2013 Compilation

@rinandia  Please do a couple things together.  First, clear Edge's Internet Explorer data, as described at the end of this article:

Next, move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  This removes, but does not delete, all your user content, including saves and store items.  You can restore it later, but for now, just open the launcher to spawn a clean folder and see whether the items will download properly.

I followed these steps. Still having the same issues. 

@rinandia  Please try downloading the items into a new admin Windows account.  Make it a local account, as in, don't sign into Microsoft, and don't sync with any other services you normally use.  You'll be able to launch Sims 3 without needing to reinstall it, but your saves and other user content won't be available.  That's not an issue though because this is just a test, and if it works, you can move the store content back to your main Windows account and install it through the launcher there.

I have all the custom content files stored locally on a flash drive already. I tried installing some of them one at a time through the launcher but it did not work. I get the following message for each item: "Installation failed: Please make sure your game has the latest Software Updates and try again."

My game is Version 1.69.43.024017. Isn't that the most recent update for PC?

Installing from the store's website is still not working.

Thank you for the help so far! Any other suggestions?

@rinandia  Did you in fact try to install the items while using a new admin Windows account?  I would suggest downloading fresh copies of your Store and custom content items as well, at least at first:  It's possible that there's a separate issue with the files you've stored, and it's best to be thorough.

Yes, I did try using a new admin Windows account. I still got the same message as before.

Hi there @rinandia,

This sounds like the live support team will need to look over your account a bit further and see why this content is not available to you- here on the forums, we don't have access to your specific account details to review this further and see what's happening. 

Please get in contact with live support from the help site here so that team can investigate your account. I'd also recommend you attach this conversation when you reach out there so that team does have something to reference.
