I have been trying to figure this out all day. I try to install MCP and Forge and get this:

I have updated python, tried this on another mac, tried to replace the lib folder, tried to replace the scala-library.jar, and tried this on windows.  Nothing has worked.  Any help is appreciated!!!

 

Thanks,

We do not support the old python setup, use the gradle version.

Which version is that?

Ok thank you.  Can I still mod without buying minecraft?  Also, did the files just move around on servers and that is why the install is not working.  If so, then does anyone know how to bypass this error?  I found the link in the EAQ and I am now wondering why it would be there if 1.5.2 is not supported.  Thanks!!!

Nevermind, Now I am using 1.6.4.  I get this error now:

What is going on!!!  I placed mine craft_server.jar in jars but it says modified server.jar detected.  Removing.  Please Help!!!

Technically yes, but we don't support those who 'crack'/pirate the game on principal.

And yes, Mojang changed things that broke the old python.

YOU WILL NOT GET SUPPORT FOR THE OLDER VERSIONS.
