Plutonium

Staff has said something like "at this time, Plutonium will not be supporting SP content.". So Join me and Bellita242 or find some friends to play through VLAN Coop SpecOps and Survival Sessions you like.

I tried by deleting all registry keys with the name called "plutonium" associated with appdata path. you can search for it with CTRL+B on the registry editor, it did work for me. Hope it does for you too.

Decime por favor que placa de video tenés, Ese es un error de Direct3D11 quizá sea tema de la placa de video o driver desactualizado.

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

check this one is Solved for W7 https://forum.plutonium.pw/topic/1367/acceso-denegado-steam_api-dll-access-denied. sorry if considered hijack but I could be useful. Bye

If you want to try this I can provide my rar file. but the answer is "Read Only" attribute on properties of such files. Good Night.

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.
