can you show a screenshot of you trying to log into the launcher?

we've tried turning off and messing around with most of the windows defenders settings, using administrator, moving the folder in a another directory, using Chatgpt to help us but non of the solutions seems to help

Go to your windows defender,find application and browser control and click smart app control settings and select off button

So this kinda happened to me to but if you already found the solution, then this is from those who don't feel like watching the video i guess. This is what worked for me tho. When you first download Plutonium, you just get the .exe file - it creates the folders and downloads everything else when you run it for the first time. Here's what to do: Create a folder for it first: Make a new folder somewhere (like C:\Games\Plutonium or on your Desktop) Move the plutonium.exe file INTO that folder This is important - it needs its own folder to download all the game files into Run it: Double-click plutonium.exe from inside that folder It will start downloading all the necessary files This includes the COD game files, which can be several GB If you get that download error again: Just try running it again - sometimes the servers are busy Or try the PowerShell command from that folder (Shift + right-click the folder, open PowerShell, then .\plutonium.exe -timeout 0)

Having this exact same issue!! Can’t for the life of me fix it

@Soulstealap right click on the empty space. select New select Folder name the folder mods Profit!

@SICOSIAO Probably injected something while online instead of using LAN mode. Any attempts to bypass bans on alts will result in more time being added onto when you'll be unbanned. Guess you'll have to wait a year 🫡

@buggedxx yes i have a solution. Press Windows+S and type "Registry editor". Open that as administrator. Expand the HKEY_LOCALMACHINE folder. Find and expand SYSTEM, then CurrentControlSet, then Control, then CI, and then policy. Click on the VerifiedAndReputable value and change it to 2 (Hexadecimal button checked. Then restart your computer. If there is no Policy folder, create it. CASE SENSITIVE. If you had to make a policy folder, or there was no VerifiedandReputable, then right click, New, DWORD (32-bit) value and name it (no speech marks and case sensitive) "VerifiedAndReputable" and set it to hexadecimal then 2

@andy238 said in Plotonium start error: ThrowForNonSuccess Cloud Flare not working for you for whatever reason.
