Music Loader Mutator

[Jofraniac]

I installed this mutator on my dedicated server hoping to conveniently serve the music files for the custom maps to the clients, but unfortunately it didn't work.
When I connect to the server and click Yes after the prompt to accept the installation of the required DLL on the client, the game just goes back to the title screen but nothing is actually installed. Now I don't really know if this issue occurs only on my system.
Does anyone know if this mutator still works with the current version of the game and on modern operating systems?

It doesn't work; the original mod by Marco used to work on a Windows 7 exploit (a very serious security vulnerability) that has since been patched. There's currently no other ways to get users to download music (ogg or mp3) as well as karma data (ka) since UE 2.5 has no support for letting clients download that stuff in game. Your best bet is to set up an in-game webpage in the "news" section with a download link that takes players to an external download page.

Well, that's a shame, but at least now I know that it's not just an issue on my end.
I've been doing exactly what you suggested with an external download link to serve the music files, not the most convenient solution, but there's nothing we can do to improve that, sadly.
Thanks for your answer, you've made things clearer to me now.

Which exact vulnerability?

Last time I checked - everything worked fine.

And even if it doesn't - you can install client files manually.

Automatically downloading a .dll file that injects itself into your executable to download specific files online. AFAIK, Marco's "exploit" only worked on Windows 7 and that was subsequently patched/removed on Windows 10. I have no idea about Linux, maybe that hasn't been patched. I remembered trying to get Marco's "Music Downloader" to work, I tinkered with it a fair bit, but couldn't get it to work at all. Then, digging around, I found some people discussing how it wasn't working on Windows 10 since it Marco was using a W7 exploit to download a .dll and inject code that way.

Yeaaah, that's what I do! I much prefer doing that tbh.

Gotcha, so it's your theory based on nothing.

Just tested on windows 11 latest / KF1 Dedicated server vanilla + music loader - everything works.

Ah Mortimer. I believe you tried that on linux which is case sensitive. no?

I wouldn't say on "nothing"; I tried on W11 and W10 and couldn't get it to work (not even on a vanilla, freshly-installed server). I think we discussed this in your server, but some mods (not specifically Scrn, but other mods) prevent the game from restarting and installing the .dll file. I've got some other users (TWI forums and Discord) expressing concern about not being able to download anything due to either an error, the game not restarting, or the .dll file not generating. This is all based on our experience!

You know the crazy thing? After you gave me a hand, it WORKED ON LINUX. I just coudln't get it to work on Windows!

It's more like mutator incompatibility, and not music loader issue on it's own.

Scrn for example has changed a lot over last few years, you can report to Poosh. So he can check what's preventing music loader to show it's gui window to clients.

In my case, after clicking Yes on the prompt, the game just returns to the title screen, but it doesn't restart. And then, if I try to rejoin the server, I get the prompt to install the .dll again.
Tested on Windows 11, by the way, but the server had a few other mutators installed, so could be a case of incompatibility between them, who knows.
