Why does JJsploit not work?

Whenever I try to attach JJsploit to Roblox, it always displays a message about missing dolls. even when I reinstall the JJsploit and Roblox, it is still the same. Example of the missing DLLs: XInput1_4.dll. My computer is Windows Seven. DISCLAIMER: when I put the dll in the JJsploit folder, it still didn't work
