api-ms-win-crt-utility-l1-1-0.dll is missing (my friend's computer).

Hello everyone . So after months i finally got my engine done. Engine uses SFML 2.4.1. Gravity simulation I made, worked fine on my computer (which runs Windows 10) without any error, but when I gave my friend a simulation, he got an error which says "The program can't start because api-ms-win-crt-utility-l1-1-0.dll is missing from your computer". http://imgur.com/a/be3lE
After that, I tried a simulation on my laptop which runs Windows 7. And I got an error but with different message. I looked at internet for solution and I found I need to install Visual C redist 2015. After installing, I tried running a simulation and got the same error as my friend. After that day, my friend told me simulation worked fine on his computer which runs Windows 10. So I concluded that build is only for Windows 10. My question is how do I make my simulation compatible for all Windows. Thanks

It seems like Windows 7 needs a specific update for VC++ 2015 redist to correctly install. I found that in 2 minutes on Google, so I assume you can easily find more details on your side

Me and my friend already tried to update as I said in text. My question is how do I make my simulation compatible for all Windows. How do I build for each version?

[Laurent]

Your application should be compatible with all Windows newer than XP without doing anything special, as long as the end user has the matching VC++ redistributables installed.

LOL
I'd say half the games I play on Steam have to download and install the VC++ redistributables

buy a game
download it
press play
wait for VC++ redistributables to install

next week --
buy a different game
download it
press play
wait for VC++ redistributables to install

couple of days later --
well, you know
