Re: My computer says it needs a certain feature to play Sims 3? HELP!!

@eryn-torrey  The first guess is that you're missing .NET Framework 3.5, or you have a corrupted installation.  Hit Windows key-R and enter "appwiz.cpl" without quotes.  In the window that opens, click "Turn Windows features on and off," and you'll see something like this:

.NET Framework 3.5 is right at the top (in blue).  If the box next to it isn't filled in, click it, and Windows should download and install it.  If it's already filled in, you can uncheck and recheck it.  If that doesn't help, run Microsoft's .NET repair tool:

(It does work in Windows 10, even though it's not listed.)

If this doesn't help either, please run a dxdiag and attach the results to a post.
