The Adobe installers seem to download OK to my desktop. I click on the download link and hit save when the pop-up box appears, although I've noticed that in Firefox, I never get the green bar 'filling up' during the download. Instead it just seems to download instantaneously. When I run the installer, the icon disappears from my desktop, and then the black Adobe update pop-up box appears. The "initializing" phase runs to 100% without any problems. But at the next step, I get the error message "download configuration failed" every time. For the Flash Player, this happens instantly, but on the Reader, it gets to 33% and then the error message appears. When I started getting the errors, I thought I'd try to fix it by uninstalling Flash entirely through Add/Remove programs and starting with the new version, but that doesn't seem to have helped, so I'm currently flashless.
I did have a virus a couple months ago--could it have corrupted something that's keeping Adobe products from updating? Or could there be something else that's conflicting with the download? My other real-time protection apart from AVG is ZoneAlarm free firewall and SpywareGuard.
Thanks for your help,
