there's your problem, you're using Windows 8. It's the worst OS out there and you should probably upgrade it to windows 10. Also I can't tell you your computer isn't meant for gaming since your storage is really low, so I think that's why it wont run properly
And it looks like a problem with your direct x installation or your gpu is just too old or onboard.
There was someone else who had the same problem with windows xp...
