Lightning could not be installed because Thunderbird cannot modify the needed file? I have limited tech ability so please help!
I have no idea what this means and how to fix it. I am trying to install Lightning to my Thunderbird so that I can share my calendar with colleagues. I am not sure what I am doing wrong?
