Generally caused by unstable internet. Try restarting your router and also make sure your windows system time and date is correct and synced.

Zezy could you provide a screenshot of your game folder and can you clarify what screen exactly it freezes on?

When they are done. No eta.

mixy same applies for you

Seems like norton has only just caught wind of it, so is blocking it. Btw I have dealt with norton in the past, it's tbh trash. It thinks everything is a virus and cripples performance. If I was you personally I would uninstall. or if they scammed you into paying for it... don't renew it.

H3X1C im not sure how do I found out?

You are complaining about a controller configuration, keyword configuration, configure it to how you like it. This has nothing to do with Plutonium as we don't supply these configurations nor support controllers yet on MW3.

Kalitos Only put them in the game folder.

Try restarting your game

Currently, there is a bug with the launcher that will prevent you from changing your game folder location, so you have to manually fix that for now.

Go to your start menu and type run
Open this program, it will show a text box, in this text box type %localappdata% then press the enter key
It will open a folder in the explorer. Now locate the folder called plutonium
Right-click and delete that folder. Now when you launch the launcher again the setup button will be visible allowing you re-select your game folder.

Provide a screenshot of your game folder

What was the specific issue you were having?

This is caused by some software running on your machine clashing with Pluto. SONAR RADAR, SONAR STUDIO, NAHIMIC, GAMERSFIRST IV, Advanced Systemcare Ultimate, and PREMIER OPINION and any other voice related / antivirus software are some of the programs that cause issue, uninstall them if you have them.
Note you may need to allow plutonium in your antivirus.
