Here is screenshot of the error message on the console.

Many thanks for your help,


What version did you install?
And was this using the regular standalone installation?
Looks like you’re on a mac. What version?

Hi Jon,

I have installed the recent version for Mac OSX with the following link:

I am on macOS Sierra version 10.12.1


I have no idea!
Do you see the splash screen appear? Any other windows become visible?
Does the icon stay visible in the dock when it crashes?
