Can't start the game

H3X1C

I didn't realise he had done that. Is your problem now resolved?

Tetsuyaa

No its didn't works i have the same message error

Emosewaj

Show your game folder again, after you repaired it.

H3X1C

Tetsuyaa Please be more specific. Which error?

Tetsuyaa

the mss32.dll

Tetsuyaa

Emosewaj

Did you even get MW3 from Steam? Why is the folder on your Desktop? Steam won't auto-fix it there.

Tetsuyaa

Yes with steam but i want make it on destkop

Emosewaj

Tetsuyaa Keep the files in Steam and place Plutonium.exe on your Desktop, in Plutonium.exe, select the Steam MW3 location as the game location.

Tetsuyaa

okey go make that

That error means the launcher is not pointed at a valid MW3 folder.

Please see this GIF that demonstrates what a valid folder looks like:

Unfortunately due to a bug in the Plutonium launcher, you are currently unable to change your selected MW3 folder. So you must fix it manually, please follow these steps:

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 it shows the setup button allowing you to re-select your MW3 folder.

Please read this information carefully and follow it exactly.

Tetsuyaa

H3X1C yeah its done with the "setup"

Emosewaj

H3X1C The error is that the folder he selected wasn't actually fixed by validating on steam because he copied it all to his desktop.

Tetsuyaa

Tetsuyaa

now i have that

H3X1C

Tetsuyaa You need a VALID MW3 install!

Your install as shown in your screenshot is not valid. You are missing files e.g. mss32.dll

Please use steam to repair your game files. Then try again.

NOTE: You cannot just download that dll from Google!!!

Tetsuyaa

What you don't understand is that I've already checked the entire game, and as soon as I put the launcher on, it takes the dll off and makes a mistake.

Tetsuyaa

@ now its works

H3X1C

Please tell us how you fixed your issue?

Tetsuyaa

yes thnks
