Don't have ff16? Not to worry - you can download the files direct from microsoft.
1. Go to
https://www.nuget.org/packages/Microsoft.Direct3D.DirectStorage/
2. Click "Download package" to download the .nupkg file.
3. Extract it. To do so, you can rename in to .zip or use 7zip or something like that.
4. Find the 2 DirectStorage DLL files in the extracted files. For most
people it will be the x64 versions, so the 2 DLL files in
native\bin\x64.
5. Go to your FF7 install directory and find the 2 DIrectStorage DLL files there, probably under End\Binaries\Win64,e .g
C:\Program Files (x86)\Steam\steamapps\common\FINAL FANTASY VII
REBIRTH\.
6. Replace the DIrectStorage DLLs in your game directory (step 5) with the newer DLLs from Nuget (step 4).
