The Sims 4 - Error downloading - Check Yes?

Make sure UAC is set to ask: http://windows.microsoft.com/en-us/windows7/how-do-i-change-the-behavior-of-user-account-control-by-using-the-slider

If that doesn't work, try starting Origin as Administrator

@mysterysimmerr

I would add a little bit to what Crin said. The UAC setting is right, but you can try it as follows: 

1. First uninstall Origin from your computer

2. Change the UAC settings to Always notify as per link that Crin provided - http://windows.microsoft.com/en-us/windows7/how-do-i-change-the-behavior-of-user-account-control-by-using-the-slider

3. Once the UAC is changed, download and install Origin and confirm all pop up windows that may show up

4. Once Origin installed, try to log in and install your games again, all should be fine now 

Hope this helps 🙂

If your problem wasn't solved and no one has gotten back to you - please either post again (or bump up your problem) or contact EA.

I just tried that but it's still not working ☹️

Sometimes cleaning out the Origin cache helps:

that sadly didn't work either ☹️

I turned off the UAC and it works now. Thank you so much :D ♥

HI @mysterysimmerr

Make sure to turn it back on after installing.
