Having issues with Dark Souls on windows 10. Help?

I already posted this on the Dark Souls subreddit, but I figured this might be a better place to post it given the technical nature of my question.

So, a while ago, I switched to windows 10, and I remember that when I had first done it I had some issues with running DS that I was eventually able to iron out. However, for complex reasons I'm not going to get into here, I had to reinstall the OS, and I'm having trouble with getting the program up and running.

So, when I click "play" from the steam menu, the message pops up saying that it's installing microsoft directx redist package, but then it just disappears and the program doesn't launch. If I go to the file in the steamapps and launch it there, I get a message saying that the program can't start because d3dx9_43.dll is missing.

I remember when I had had these issues before, there was just some directx thing I had to install manually somewhere, and from then on, it would work, but I can't find where to get it. I keep seeing people linking to some "DirectX end-user runtime web installer" but whenever I click that, it takes me to the media creation tool for windows 10, which is clearly not what I'm looking for. Does anyone know what I need to do? I've tried finding the dll files, but the most I've been able to do is make it give me a different error. If I put the 64 bit version of D3DX9_43.dll which I found online into the "DATA" folder, I get a message saying "The application was unable to start correctly (0xc000007b). Click OK to close the application". Does anyone know what I need to do?

Nevermind, I was able to find what I needed to install by googling dxwebsetup.exe. I'll leave this here though in case anyone who had the same issues as me finds it useful.

Bro thanx for leaving this post online.. I've done a lot of research about DS on Windows 10 and your post seems to match my problem.. May I I asked what exactly you did after googling dxsetup? Were you able to play the game with dsfix and unlocked fps??
