My ati radeon hd 2400 xt won't install on windows 10 x64 bit its shows Components are already installed.
If you are trying to install newer drivers they won't install. AMD dropped support for that card a GPU a very long time ago. Likely that the only driver that will ever work is the one that might come with Windows 10. If you are on a laptop you're out of luck on a desktop you may be best to buy a new card.
