multi-clienting

Do I need to make tutorial for dual logging in? Lol
Cause I always play other mmorpg game, dual logging in by using sandboxie.

please Misterceez, I've downloaded sandboxie and i've no diea how to dual client.

This is a game using a singleton process which means that the files can only be used but the application once. No multi-clienting is possible unless you modifie the main files.

So finding Mutex or something like that through Ollydbg is not possible? What main files do you mean?

For starters the program loader is programmed to check the files contained in the aeriagames folder and finds the ones that are corrupted and replaces them with a fresh copy. After that you need to change the actual game template classes and classes so that they can be used in more than one instance... singletons are one time uses of objects, they suck.
I'm pretty sure there is a way... which one it is, this is too far ahead of my project to tell .

Okay okay, here I made the tutorial how to dual login by using sandboxie.

you don't need to edit files or shet.
all you need are just 2 files of eden eternal. The original one in the default place, and the other one in the desktop.

I keep getting this message..

same with me but sometime i can open it well and replace all the files that u said and when i click on the Start button it says ( EDEN ETERNAL HAS STOPPED WORKING A PROBLEM CAUSED THE PROGRAM TO STOP WORKING CORRECTLY WINDOW WILL CLOSE THE PROGRAM AND NOTIFY YOU IF A SOLUTION IS AVAIVABLE ) I have Window Vista 64Bit plz help i really need dual client really bad T.T

You need to run the sandboxie as administrator.
Cause if you didn't you'll get the message like @Flukeshotz does, and the game might crash too.

I did run as Administrator..

thank you i turned off what so called drop rights restriction...
