Mr. Android

Intro:
Thanks for interest in Plutonium! To see what we've changed in Plutonium IW5 checkout:

Get the actual IW5 base game:
Please ensure you have the actual IW5 game, Steam will provide this to you for FREE, check this thread for instructions on how to get it. https://forum.plutonium.pw/topic/448/how-to-download-the-iw5-base-game

Plutonium uses the latest IW5 version, as such we highly recommend using Steam to get the latest copy and avoid errors that older copies will cause. We will not provide support to old copies, we are busy enough as it is. The Modern Warfare 3 Dedicated Server files as shown in the linked thread or the actual Modern Warfare 3 Multiplayer files (from an owned copy) are perfectly fine.

Get the DLC:
It is recommended you download the DLC to enjoy the complete MW3 experience and also for the fact that lots of servers have DLC maps in rotation. You can download the DLC from one of the following links, please read the readme.txt for installation instructions (It's in the zip):
Gdrive: https://drive.google.com/open?id=1fOXq1BFSn_FT1o8SZUzNnzAQDxdb7Ip2
or

Warning:
The Plutonium Launcher and IW5 / T6 Mod are created by a group who make this as a hobby, as such, we cannot afford Code Signing certificates (roughly $500 for a reputable one), this means when we release updates, plenty of AntiVirus products will see our newly created files with no Code Signing as suspicious. Plutonium also keeps itself up to date and sends requests to our servers to grab the serverlist and to talk to our anticheat, this also causes AntiVirus products to mark us as malicious. As such we get many support requests due to AntiVirus deleting our files - we, therefore, provide instructions and files below to add Exclusions to Windows Defender for Plutonium if you require them. Some players find that their Windows Defender doesn't complain whereas others players struggle.

How to install Plutonium IW5:

This guide assumes you followed the step above and Steam installed the base game to C:\Program Files (x86)\Steam\steamapps\common\Call Of Duty Modern Warfare 3
Browse to https://cdn.plutonium.pw/updater/plutonium.exe and download the file. If your web browser blocks the download or removes it then you will need to tell your web browser to ignore the detection and keep the file. If Windows Defender blocks or removes the file then please download the file linked below and run the .bat file as Administrator. This will add the needed exclusions. https://cdn.discordapp.com/attachments/697719316187054100/771733688575983677/Exclusions.bat
Open Plutonium.exe (you shouldn't need to run as administrator) and you should see it start to check for Launcher updates and download any that are required as shown below. SmartScreen may appear warning you about the file, click the "more information" button and then click "Run Anyway". This should only appear once.
After this you will be shown a login screen, enter your Plutonium Forum Username and Password and login. You will need to login every 2 weeks. We are working on auto-renewing the login so you don't have to do this in the future. This login is case sensitive!
Ensure you are on the MW3 tab (it should look like the below image) and then click the Setup button. You now need to tell the Launcher where your copy of MW3 is stored, if you followed the guide in step 1, this location will be C:\Program Files (x86)\Steam\steamapps\common\Call Of Duty Modern Warfare 3
Once you've selected your game location it should change to a green Play button.

All Done:

Click Play and enjoy the game! This may crash on the first time, this is expected, simply launch again and you won't get the error! Click the servers button on the main menu of the game to view all the servers to play on.
To start Plutonium IW5 in the future, simply open Plutonium.exe - We suggest adding it to your Start Menu
Click the cog icon just to the right of the play button to change the base game path at any time.
