Windows standalone build not working on windows 10

Hi I’m using Unity 5.3.2 on windows 8.1. I tried building a standalone for my client who uses windows 10 but he says he cannot run it. After he double clicks the exe it just loads infinitely and it doesn’t show in the processes.

Is this an issue with unity or his win 10?

I’m fairly new to unity and I haven’t tried building for windows 10 yet. I was just wondering if you are able to play the standalone builds or do I have to switch to Windows Store platform.

I also have this problem and a few others do too. It isn’t being answered anywhere.
