Problems with using 'Examine CT' option

Hi,
When I try to use the 'Examine CT' function, I get an error which says 'no module named enable.component_editor'. I searched about it and now I think that I need a specific version of some graphics library to make it work. I am not sure but it looks like I just need the right version of some software. Would you be able to tell what I should do?

Thanks a lot
