Missing XIUNPUT1_4.dll

I have had zero problems with this game until today.

Now when I try to start I am given the error:

"The program can't start because XINPUT1_4.dll is missing from your computer. Try reinstalling the program to fix this problem."

I have uninstalled/reinstalled BG:A. I have followed all the steps in your technical FAQ. I have tried using the UE4 Prerequisites exe. I have tried downloading a dll from the web (which just changes the error message).

As far as I know nothing has changed in my system over the last day, no uninstalls, updates, nothing.

I am running Win7 x64, DxDiag attached.

Hoping to get some help on this, thanks


EDIT: I can solve this problem by copying and renaming the xinput1_3.dll. I'm then warned that XAUDIO2_9.dll is missing. My research suggests this is something to do with the engine having been patched and no longer being compatible with Windows 7. Is this the case, and if yes then will a workaround be produced?

So it's been like 6 months, and not a word from Focus, while this issue still exists? Yeah, starts to look like it's abandoned at this point, such a shame...
