I was going to ask this on the sims forums but i dont know how to make a post on there. Anyway i havent played the sims 3 in a long time and wanted to play again. Every time i press play on the launcher it brings up an error saying missing file d3d9.dll. I have absolutely no idea what that is or how to fix it. Ive looked everywhere for it but am at a loss. Can someone please help?
@Ari204406 Within TS3's program files, look for DXSETUP.exe. I'm not sure what kind of install you have, but it should be in there somewhere. For example, on my Steam install, the path is:
Program Files (x86)\Steam\steamapps\common\The Sims 3\install\Directx
For an Origin install, it will look something like this:
Program Files (x86)\Origin Games\TS3\_Installer\directx
Run the .exe as an admin, then restart your computer.
If that doesn't help, you can install the file directly from Microsoft:
If that doesn't work either, are you running SweetFX, by any chance? It uses altered dx files, so that could be interfering with TS3.
By the way, you can only start a new discussion on the official Sims forums if you're a full member, which means having 15 posts and 25 points. Otherwise, you'd need to post in an existing thread, like the one for new members. But posting here is also fine.
(Thanks to @Holger1405 for the consult.)
@Ari204406 Please run a dxdiag and attach the results to a post here. That will cover a lot of ground at once.

@Ari204406 The driver for your graphics card is over three years old. You can download the newest version from Intel:
If that alone doesn't help, you really do need to install DirectX, not just download it.
I'm not sure what the person you talked to meant about not downloading the file, but it's perfectly safe to download from Microsoft or other manufacturers' websites (like Intel's, in the link above). That's the only way to get the newest updates. And since Windows 10 updates automatically, your other software needs to be updated as well to remain compatible.
Once you've installed the new driver and DirectX, try to launch TS3 a couple more times, and if it still doesn't work, run another dxdiag.
(Thanks again, @Holger1405 .)
@Ari204406 d3d9.dll is part of DX12. Previous versions of DX (directx) will not work with Windows 10 (at least not well if at all). The only way I found to reinstall DX12 is from the Windows 10 install files (which is not easy). A guess you installed something that may have corrupted the DirectX 12 install. You could try to google how to reinstall DX12. I saw some posts that may help.
