Bad Image Error: JJSploit

I need some help with a error that is occuring. Everytime i try to attach JJSploit to a Roblox game, it says

"JJSploit is not designated to run on Windows or has an error."

I cannot remember the whole thing, but yeah. Is there anyway i can fix this? I tried to move it into System32, but it does not work. I also have a Windows 10, so yeah.
