Bug Code execution cannot proceed because UnityPLayer.dll was not found

Before launching a demo of a game I am making, I got to test the build in several machines and everything worked perfectly.

However, on my friend's machine (a Windows 11, the same as mine) it does not even launch reporting the error in the title: "Code execution cannot proceed because UnityPLayer.dll was not found. Reinstalling the program may fix this probem". He had indeed reinstalled the program various times. Furthermore he has all the files in the same folder, the way you should run unity games, I attached a picture of it:



I developed the game with Unity 2021.2.7f1 and both exported and tested it on Linux and Windows.

 

Thanks for your advice and sorry for the delay in my response.

I finally solved my issue by generating another build and ignoring the previous one. But still it's a clever idea to check for file extension duplication.
