Is Eclipse plugin compatible with latest XULRunner?

When I am trying to open java file with Vaadin Editor, I am getting the following error:

Could not start XULRunner (version 1.9 or higher required)
OS: Windows 7 Prof x64
Eclipse: Indigo
XULRunner: 6.0, it is just unpacked into some folder, not installed; PATH added.

So, how to either install XULRunner for Eclipse Vaadin plugin, or how to tell Vaadin plugin where XULRunner is located?

It is said that XLURunned does not suppurt system-wide registerning from version 5.
