Version 19.0 Error:Error opening File for writing HELP!!!!

Can some one help me im trying to update my Comodo Ice Dragon but the error keeps coming up! I really need some help this my usual every day browser and my favorite!

Hi and welcome Dexl,
What is your Windows version?
Have you tried disabling all 3rd party Add-ons?

Is the Comodo IceDragon Updater Service running and set to automatic?
Type Services.msc in the search box of Windows start menu then enter, scroll to the Comodo IceDragon Updater Service to check its status and settings.
If yes try opening CID as administrator, right click run as administrator and try updating.

If the above fails, I would suggest uninstalling CID and re-install with the latest version.

Kind regards.
