Kodi 17 on a Windows 7 computer

I just installed Kodi 17 yesterday and I noted on the download site it said for Windows 10. However my computer is running 7, and I tried watching a video but it froze up after a few minutes with a 100 in a circle in the middle of the screen. I tried starting a few times and it happened every time. Do I just need to go ahead and upgrade to 10? Or could it be another issue?
