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 FilesEclipse-SDK-4.2-win32-x86_64eclipseeclipse.exe” -vm “C:Program Files (x86)Javajre7binjavaw.exe”

Answer
There are working combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.
Use one of the following combinations.
- 32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)
- 64-bit OS, 32-bit JDK, 32-bit Eclipse
- 64-bit OS, 64-bit JDK, 64-bit Eclipse (64-bit only)
