I have Minecraft saved to my desktop and it runs beautifully.

I have a folder on the desktop also, named 'World of Minecraft', with the extracted files from 'womclient-1.5.9.zip'.

I have downloaded 'minecraft.jar' from http://minecraft.net/download.jsp and saved it in "C:\Users\*username*\Desktop\World of Minecraft\lib".

When I run 'run.bat' I get the following error: Exception in thread "main" java.lang.NoClassDefFoundError: com/mojang/minecraft/MinecraftApplet

I have also copied the 'minecraft.jar' file from "C:\Users\*username*\AppData\Roaming\.minecraft\bin". Both of the minecraft.jar files I used have different file sizes. Running 'run.bat' with either of these minecraft.jar files produces the exact same error message above.

Is there something I am not doing correctly? Do I have files in the wrong location? Any help would be appreciated.

That's not the right one.

That's not the right minecraft.jar file. You need the classic one, located here: https://s3.amazonaws.com/MinecraftDownload/classic/minecraft.jar

Thank you very much for the

Thank you very much for the reply. This is the exact information I needed.

I was following the instructions in the 'Readme.txt' file included in the World of Minecraft zip file, which tells you to go here: http://minecraft.net/client/minecraft.jar

Thanks again :)

Of course.

Of course. My evil runs unparalleled, unless I am feeling helpful. Make sure to eat plenty of fruits and vegetables, and stay out of trouble! :P
