Coding: Error running Eclipse with 32-bit Java

I get this error because I had Java 32-bit running and a 64-bit version was needed.

Java was started but returned exit code=13

I had Eclipse and Java installed a long while back, and was pretty sure that Eclipse was working before distracted by other projects. Coming back to it to work with Google Apps, I received the above error. After some trial-and-error, I finally found a post that it may have to do with the Java version. I had to download the 64-bit version. I am not sure why I thought Eclipse had worked before. Whatever I had thought, the 64-bit version of Java fixed this above error.
