Hello there!

This being my first time here I'm not really sure how you do things here.

 

So I'm using the latest version of MCP and the recommended build of forge.

I have downloaded minecraft.jar of http://assets.minecraft.net/1_3_2/minecraft.jar and minecraft_server.jar from http://assets.minecraft.net/1_3_2/minecraft_server.jar

I then did as I normally would  - placing the bin folder into jars, replacing the minecraft.jar, placing minecraft_server.jar.

 

But when using the install.bat file that came with forge, I ran into this problem

"Modified Client detected"

Then MCP also warned me that it was modified - which was wired, since I downloaded it from the said-before URL.

And then, when running MCPMerger, the following error happened:

Press any key to continue . . .

 

 

What should I do?

Did you install forge into the client? 

No... like I said, I used the one I downloaded from assets.minecraft.net

Give us a full console log.

I currently cannot, I'll post it when I get a chance

Here it is

Seems fairly obvious what the error is to me.

okay.

So I tried this.

 

Backup minecraft.jar

Force update

Drag bin file into jars file

run install.cmd

 

the exact same error happenned, with the exact some log.

Modified jar how?

Dont know how you're doing it, but if it says you're using a modified jar, you are.

Start from scratch.

They wont help you the have theyer protocoll. when there stay modifiered jar than they stop reading. do it the old way. download forge client. put it with modloader in the jar. delete meta-inf and decompile it. that work. the forge installer is broken. and if they delete the comment i pm you.

The installer is not broken, it works fine if you provide valid clean jars.

DO NOT install ModLoader EVER

ModLoader is NOT needed for Forge it WILL break shit because it is horribly written.

You know what, Speiger, I'm tired of your stupidity, get off my forum.
