I recently started receiving error messages when trying to open pdf files. I uninstalled my adobe reader and then tried to reinstall. I keep getting error messages telling me that I need a newer version of windows. I have windows XP Service Pack 3. It keeps telling me that I need windows 2000 or newer. I have been working in the support module for over a week and cannot seem to get my problem solved. Can anyone out there help with this problem? Why is it telling me I need windows 2000 when the screen allows you to select windows XP? Thanks.
