[FIXED] Eclipse failing to open

Issue

My Eclipse IDE keeps failing to open. I've updated my java to the latest version, I've got the newest Eclipse Version. I'm running x64 Windows, it seems like the Error log is trying to use x32, but I've installed a x64 version of Eclipse. I tried re-installing the x64 version and it still didn't work.

In the Pastebin I've linked is the contents of the Log.

EDIT: I'm using x64-bit version of Java

Solution

Thank you for copying/pasting the log - definitely helpful!

This line looks significant:

Caused by: org.eclipse.core.internal.resources.ResourceException: Incompatible file format. Workspace was saved with an incompatible 

SUGGESTIONS:

1. From a command prompt:

   • cd into your Eclipse directory

   • type eclipse -clean -clearPersistedState

2. Rename (or delete) any old workspaces to force Eclipse to create a new workspace
