Can't start Eclipse - Java was started but returned exit code=13

I am trying to get my first taste of Android development using Eclipse. I ran into this problem when trying to run Eclipse, having installed version 4.2 only minutes ago.

After first trying to start Eclipse without any parameters to specify the Java VM, I got an error message saying it couldn't find a Java VM called javaw.exe inside the Eclipse folder, so I found where Java was installed and specified that location as the parameter in the shortcut's target. Now I get a different error, "Java was started but returned exit code=13".

Similar questions seem to indicate that it's a 32-bit/64-bit conflict, but I'm 99% positive that I downloaded 64-bit versions of both Eclipse and Java (RE 7u5), which I chose because I have 64-bit Windows 7.

If anyone knows how to confirm that my Eclipse and Java are 64-bit, that'd be appreciated.
If you think my problem is a different one, please help!
Please speak as plainly as you can, as I am totally new to Eclipse and Java.
Shortcut Target: "C:\Program Files\Eclipse-SDK-4.2-win32-x86_64\eclipse\eclipse.exe" -vm "C:\Program Files (x86)\Java\jre7\bin\javaw.exe"

    Your version of Eclipse looks OK, based on the filename.

    To check your version of Java, run

      java -version 
    in a console (command prompt). On Windows 7 with 64-bit Java 6 I get:

      java version "1.6.0_27"
      Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
      Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)
    Note the 3rd line, which shows that this is a 64-bit version.

    On a 32-bit version you'll get something like:

      Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing) 
    Check that this is the version being used by Eclipse, as shown in your error code. If not, call that version explicitly, by running the following command in a console (command prompt):

      "C:\Program Files (x86)\Java\jre7\bin\java.exe" -version
    (using the correct path to java.exe as shown in your error message, not necessarily the path shown in my example above!)
