PLEASE HELP! Dolphin 3.0 64bit will not work

[PurpZilla]

Alright.. call me an idiot. I just did.. once again... another clean install of windows 7 ultimate. I have added no programs. Just got done installing ALL windows updates which I hate, and have installed the correct, most up-to-date version of vcredist. The dll files aren't there that supposedly should be according to you fools, and so please explain why they aren't if i have done everything correctly and exactly like everyone has said, and why nothing is changing. Still getting a 'xinput1_3.dll' is missing. I downloaded the 2012 version of the dll, placed it in my C:/windows/system32 and it gives me the wonderful 0xc000007b error message. ????
