Plutonium

It's currently not planned, MP is the focus for IW5. That may change in the future though. Its a fair bit of work to get working though.

Whiskee Can you confirm the launcher requires DirectX11? If so, can we reduce that requirement?

Zeak I can see you tried to show your applications, could you add them to an imgur.com album and send here or to my discord? Mr. Android#9053

Revin Have you got Nahimic installed? If so, uninstall it.

RektInator We had a widescreen fix in 2017, right? Could that help if we add it back eventually?

Try running plutonium.exe as an administrator.

If that doesn't work - add %localappdata%/plutonium as a folder exclusion in Windows defender. Maybe defender is blocking the download.

Sasymara Can you show us a screenshot?

switch Just to confirm, what did you change? the polling rate or the process priority?

Gotta reduce your mouse polling rate.
You can also try changing the game process priority in task manager, mw3 sets it to high, try setting it to normal.

Revin Tell chrome to ignore the alert and then run it as administrator.

@Korinzurabu said in Bootstrapper pops up but mw3 wont launch:

So if you have Nahmic uninstall it i uninstalled nahmic and it started working for me

This sounds about right, everyone who has fixed this has said it's something to do with software that modifies your sound or microphone.

Wonderful - have a good day and thanks for letting us know.

No worries, let us know how you get on.

Zeak OK, thanks for letting me know.

Try again in a few hours when the servers arn't as overloaded and if it still fails send us a screenshot of your MW3 folder.

Some people with long passwords have setup an AutoHotKey script to paste their clipboard. That may help.

If everyone with the problem can post their installed programs, it will help us see if there is something in common.

Known problem and will be added in a future update. Thanks for the report though.

RektInator Any idea? Should the .DSL file be in the main folder? Any reason blindw32.dll is being deleted do you think?

Did you point the Plutonium Launcher to your tekno mw3 install? If so, that's likely the reason, it runs on a much outdated version of MW3. I'd suggest downloading MW3 via the dedicated server on steam, we have a guide binned in these forums.
