Eclipse gives “Java was started but returned exit code 13” [duplicate]

Answer 1

It would be the 32 bit version of eclipse , for instance if you are running the 32 bit version of eclipse in 64 bit JVM, this error will be the result.

To confirm this check for log in your configuration folder of the eclipse. Log will be as following java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM ...

try installing the either 64 bit eclipse or run in 32 bit jvm
