Hello LexManos and Ariath, Thanks for your replies ! @Ariath : this is a possibility, but i don't like to modify directly the FML code @LexManos : yes, i have read the MultiMC source code, and others source codes (like Technic Launcher ...) The problem is partially solved. I have added this line : System.setProperty("minecraft.applet.TargetDirectory", Util.getWorkingDirectory().toString()); // getWorkingDirectory : return the folder where my launcher have downloaded files, so it's good When i launch the launcher in Eclipse, this works very well, no error messages ... but, when i create the Runnable JAR and when I click to the "Connect" button, this error message appears : 2013-05-21 18:15:29 [sEVERE] [ForgeModLoader] Found unknown applet parent net.mi necraft.Launcher, unable to inject! 2013-05-21 18:15:29 [iNFO] [sTDERR] Exception in thread "Thread-5" java.lang.Run timeException: java.lang.RuntimeException 2013-05-21 18:15:29 [iNFO] [sTDERR] at cpw.mods.fml.relauncher.FMLRelauncher .relaunchApplet(FMLRelauncher.java:287) 2013-05-21 18:15:29 [iNFO] [sTDERR] at cpw.mods.fml.relauncher.FMLRelauncher .appletEntry(FMLRelauncher.java:229) 2013-05-21 18:15:29 [iNFO] [sTDERR] at net.minecraft.client.MinecraftApplet. init(MinecraftApplet.java:25) 2013-05-21 18:15:29 [iNFO] [sTDERR] at net.minecraft.Launcher.replace(Launch er.java:146) 2013-05-21 18:15:29 [iNFO] [sTDERR] at net.minecraft.Launcher$1.run(Launcher .java:90) 2013-05-21 18:15:29 [iNFO] [sTDERR] Caused by: java.lang.RuntimeException 2013-05-21 18:15:29 [iNFO] [sTDERR] at cpw.mods.fml.relauncher.FMLRelauncher .relaunchApplet(FMLRelauncher.java:282) 2013-05-21 18:15:29 [iNFO] [sTDERR] ... 4 more Thanks for your replies !

Hello all ! Today i'm creating a launcher for me and my other friends. The launcher is very simple, just enter MC informations and click "Connect". Everything works normally, but Forge doesn't load mods from the good folder. For my mods, i've created a new folder : %APPDATA%\.custom\152\ (with instMods, mods etc ...) but Forge loads mods from .minecraft\mods\. Is there a argument to make forge choosing the good mods folder ? (in my case %APPDATA%\.custom\152). Thanks by advance ! OverSpeed301.
