android - Setting up Eclipse and Java JDK

I've been attempting to install and set up the Java JDK 1.6 and Eclipse (helios) on Windows 7.

I have downloaded the 32 bit of each, as the 64 bit Eclipse version didn't want to work.

So, having done that and amended the eclipse.ini file to pick up the right java.exe, I'm getting exit code 13 when running Eclipse. Have I made an error in the eclipse.ini some place?

Thanks!
