I have a HP Download Manager installation file. When I try to install it, it says It cannot be installed in a system with NET Framework under version 3.5. I have installed NET Framework 4.0 beta version, yet it is displaying the same message.
It's possible that you need to re-install HP Update to detect the NET Framework installation again. Restart the computer after each installation to properly install all the necessary files that might be in use and then the application will work normally.
