The readerr opens if I want to view documents I've got on my hard disk but when I'm on the internet they fail to open.I've changed the settings so that pages can be viewed directly frominternet Explorer but still the files won't open.Windows Xp
The problem arises when you update Internet Explorer. IE holds plug-ins from Acrobat and other programs which allow them to use or be incorporated with IE. When you update IE, it removes the plug-ins and these must be replaced by re-installing Acrobat Reader, etc. Hope this helps.
