The application did not start correctly (0xc0000102) Click OK to close the application.

So I tried to start Wallpaper Engine (Without Admin It worked without admin and I can play Online steam games without admin aswell) but as I try to start it doesn't open. Then I opended it on the Explorer app under : "C:\Program Files (x86)\Steam\steamapps\common\wallpaper_engine"
And clicked the 64x version. It didn't open but my Background changed and it was the one I used. Then I opended the arrow pointing up on bottom right and right clicked on Wallpaper Engine and then pressed settings. It said then : "The application did not start correctly (0xc0000102) Click OK to close the application."
Any advice to fix this situation?
It would be really nice.

Make sure the app is turned off, then try to verify the application files:

If that does not work, then likely something is interfering with Wallpaper Engine, usually an antivirus app. Make sure any antivirus app ignores your entire Steam directory and then reinstall the app entirely.

If the issue still persists after having made sure no antivirus app is blocking Wallpaper Engine by mistake, you can run our scan tool and share the log file it creates as outlined here:

I fixed it, somehow the DLL "d3d11.dll" got deleted. I found this out after I tried opening it without steam. I then downloaded the latest version of the DLL and now it works, if it happens to you, then go download the DLL at : https://www.dll-files.com/download/435affc523144df1c68a5576210b1380/d3d11.dll.html?c=c2JsNGNUcGI5bWVGUUpaSnlpNDliUT09

Here is the path way : C:\Program Files (x86)\Steam\steamapps\common\wallpaper_engine\bin
Insert the d3d11.dll there.
You can only open Wallpaper engine with the path way : C:\Program Files (x86)\Steam\steamapps\common\wallpaper_engine and then Wallpaper64
