To resolve this I would suggest you to turn off any Anti-virus, system optimizer, internet and browser security software installed on your machine and then retry the update.
For many customer's ByteFence has been creating this issue, refer to this thread to know more: Creative Cloud update Fatal Error '116" , so if you have this software installed on your machine then please uninstall it and retry.
This isn't a way to do thing. Creative Cloud is "profesional" software, it should work in a professional environment, with professional anti-virus and professional security. Why should we disable every security on our workstation to accomodate Adobe ?!?
