My Sims 4 will not launch.

@lauraubels  The Sims 4 errors in your dxdiag (and the Origin errors as well) are most likely related to the driver for your graphics chip.  Since you already have the newest one offered by Acer, try doing a clean uninstall and reinstall of the driver.  Download Display Driver Uninstaller from here:

You can get a fresh copy of the Intel VGA driver here:

Next, take your computer completely offline—disable wifi and/or pull the ethernet cord—and double-click the DDU.exe.  Take note of where the file will land, and click Extract.  If it's easier, you can copy the path and then paste it into the address bar in a File Explorer window.  Open the folder and then launch Display Driver Uninstaller.exe, and you'll get a message that you're not in Safe Mode.  Click OK, then go to Options and enable Safe Mode dialog.  Here's a screenshot of what your options should look like; make sure the box in red is checked:

Close options, and the DDU, and then open the DDU.exe again.  For launch options, choose "Safe Mode (Recommended)," and then click Reboot to Safe Mode (you'll need your password, so find it before rebooting).  Once you login, you'll see this:

In the blue box, choose GPU, then Intel if it's not already showing.  Then click Clean and Restart (red box).

Once your computer has rebooted, now back in normal mode, run the driver installer as an admin: right-click on the download and select "Run as administrator."

Restart again, go back online, and test the game.
