I have had and used Adobe Flash Player on my pc for some time. I am using Windows 7. Many, but not all my video graphics ask me to update. Recent weeks/months I have been attempting to use the Adobe updater without success. We get to the rectangular graphite colour box, 'Adobe Flash Installer' and nothing. I use Firefox and Avast Free Antivirus. I do not show Adobe Flash Player as a programme on my system now for some reason, so cannot remove and re-install. From what I can see it is not set up to block any Adobe updates. Please someone at Adobe talk to me!!
