Why Does Eclipse Fail to Start with Exit Code 13?

Eclipse Unable to Start: Exit Code 13

Problem Description:

Attempted installation of Eclipse for Android development encounters an error upon launch, with the message "Java was started but returned exit code=13."

Analysis:

The provided log indicates that Eclipse is attempting to use a 32-bit version of Java (located in "Program Files (x86)") while Eclipse itself is 64-bit.

Solution:

Confirm Eclipse and Java Versions:

1. Check the Eclipse version path:

   • The mentioned path "Eclipse-SDK-4.2-win32-x86_64" indicates a 64-bit version.

2. Check the Java version:

   • Open a command prompt and run "java -version."
   • The third line of the output should indicate "64-Bit Server VM" or "64-Bit Client VM" for a 64-bit version.

Resolving the Conflict:

1. Specify Explicit Java Path in eclipse.ini:

   • Open the eclipse.ini file located in the Eclipse installation directory.
   • Add the "-vm" option with the path to your 64-bit Java executable (e.g., "-vm C:Program FilesJavajre7binjavaw.exe").

2. Use 32-bit Eclipse:

   • If you have a 32-bit Java installation, you can alternatively download and use the 32-bit version of Eclipse.

Additional Recommendations:

1. Uninstall Unused Java Versions:

   • Remove any unnecessary 32-bit Java versions to avoid confusion in the system path.

2. Specify Java Path in eclipse.ini:

   • Specifying the Java path in eclipse.ini is recommended to prevent path changes from affecting Eclipse's functionality.
