Plutonium

Hi, Well I'm here to say that I was able to fix the "Access Denied: Steam_Api.dll" error on BELLITA242's PC (WIN7 X64 SP1) I installed same updates, same, net framework releases and same visual c++ releases I have on my pc in comparisson on her PC, which not. Maybe that help, but the real success test on IW5 lauching with Plutonium was to rar all of MW3 root files (No folders) and copy that rar into her MW3 root folder. And it works! But I really think is to uncheck the "Read Only" box on the properties of each one of that files I compress to transfer.
I post this just to help other people with same problem, and people with WINDOWS 7 TOO, which is really working for US.

Quizá borrando la carpeta plutonium ubicada en "%usuario%\appdata\local" y ejecutando nuevamente el update laucher "plutonium.exe" ojalá te sirva. un saludo
