I just edited my post when i have deleted 4096 fix it works fine, howewer thank you, i keep in mind.

Thank you for your quick response, but i want to have mystcraft, do you know i can download MC Forge ver 3.3.7.135 ? I was thinking that when i've deleted optifine it works fine. I have deleted 4096 fix and minecraft launched correctly.

I have installed Minecraft forge version 3.3.8.152, Optifine, IC² and various mods. When i start minecraft, iget an error of IC² that say : 2012-06-27 09:13:19 [sEVERE] IndustrialCraft 2 Error === IndustrialCraft 2 Error === Minecraft Forge is not properly installed. Possible reasons include: * Minecraft Forge is not installed at all * Minecraft Forge is installed in the mods folder instead of inside the minecraft.jar or minecraft_server.jar file * One or more mods have been installed in the wrong order * One or more installed mods are incompatible with the Minecraft Forge IndustrialCraft 2 needs the Minecraft Forge to be properly installed in order to operate. (Technical information: Missing hook Block.isGenMineableReplaceable) In the jar i got the following mods in this order : MC forge mDiyo's 4096 fix 1.2.5 v4 mystcraft 0.8.6b (forge 3.3.7.135) Code chicken core 0.5.3 NEI 1.2.2.4 sparrow 1.1.0 Optifine HD MT C3 Single player commands 3.2.2 In the mod folder i got all the mods of Direwolf20 plus BC/IC converter and transformers for industrialcraft 1.95. Industrialcraft is on version 1.97. This the content of the ForgeModLoader-0.txt file. Thank you in advance for your future help. Sorry fo my bad english I'm French.
