the steps i have done to install forge:

1. putted mcp in an folder

2. putted forge in the same folder

3. putted a fresh minecraft bin in the jars folder

4. putted a fresh minecraft server.jar in the jars folder

5. stared install.bat in the forge folder

You need to close any text editors, etc, you have looking at MC's source, if that doesn't work, start afresh in a new folder.
