in my desktop

I run it as admin and nothing happen. I tried to remove and download a second time plutonium, and that's the same thing. My path is : C:\Users\Romansky\AppData\Local\Plutonium

I cannot make the filepath between plutonium and my MW3 Files, because the launcher close immediately when I click on setup

Hi, my plutonium launcher close when I click on the button setup and there is nothing appear after that. Someone can explain my problem please ? Thanks
