1.6.2 crashed after installing forge

[crazyyankee11]

i installed forge and i wanted to see if everything was working, when i start up minecraft under the forge jar, the message i get is

 

 

[sEVERE] [ForgeModLoader] Technical information: The class net.minecraft.client.ClientBrandRetriever should have been associated with the minecraft jar file, and should have returned us a valid, intact minecraft jar location. This did not work.

 

 

please help

[LexManos]

How did you install Forge?

Did you use the installer?

The issue is that it can't find the ClientBrandRetriever class which should be inside the unmodified minecraft.jar.

How are you running the game?

[crazyyankee11]

i went a installed the latest installer from the files part of the website.

 

yes i used the installer

 

i run the game by opening the minecraft launcher, chosing the forge account, making sure it has the forge .jar chosen, i hit play and then i recieve that message.

 

i  have gotten that message every time i try to install forge. i have tried today, last week and about a month ago with all different versions of forge and have gotten the same message each time

 

i followed this video

[LexManos]

Have you ran 1.6.2 in the new launcher before installing forge?

[crazyyankee11]

yes i have

[LexManos]

Did you edit the jar? If so why?

[crazyyankee11]

Try running vanilla 1.6.2 then re running the installer, else really go check if there is something else in the jar that shouldnt be there.

[crazyyankee11]

i ran vanilla, then i ran the forge version. still crashed and when i opened the jar up idk what is and isnt supposed to be there, the only think i know that is not there is the meta-inf folder which i dont think its supposed to be there

[GotoLink]

If no meta-inf folder was here, you didn't run from an unmodified jar.

Get an unmodified jar and redo the installation.

[crazyyankee11]

how do i know what is an unmodified jar? i have tried 4 different version from the files section of these forums, the 3 newest at the time and the recommended

[luacs1998]

Meaning, don't touch your minecraft.jar.

[crazyyankee11]

i dont touch my .jar at all. i never have and i dont plan on it.... even with the new copies that i download and install

[MTPetey]

Delete the jar, or the whole 1.6.2 version folder, and let the launcher download a new one by selecting the default account. Then install forge again, and run the forge profile.

[crazyyankee11]

alright ill try it. and you mean deleting or removing my 1.6.2 vanilla version folder?
