Trying to download adobe reader and I get this message before it finishes downloading. Installation package could not be opened verify that the package exists and that you can access it or cantact the application vendor to verify that this is a valid windows installer package. Not sure why it wont work, new computer with windows 7.
That sounds as if you already have a (corrupted) version of Adobe Reader on your system. Remove it with the Windows Installer Cleanup Utility (http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.html), then try again.
