Your card is considered to be "legacy" (OLD). Since you didn't post your computer specs, need to go here to download the last known supported driver for your HD6450 : Download Drivers .
This is what AMD says about your card from Driver download:
AMD Radeon™ R5 235X, Radeon™ R5 235, Radeon™ R5 230, Radeon™ R5 220, Radeon™ HD 8470, Radeon™ HD 8350, Radeon™ HD 8000 (D/G variants), Radeon™ HD 7000 Series (HD 7600 and below), Radeon™ HD 6000 Series, and Radeon™ HD 5000 Series Graphics products have been moved to a legacy support model and no additional driver releases are planned. This change enables us to dedicate valuable engineering resources to developing new features and enhancements for graphics products based on the GCN Architecture.
As a courtesy to our valued supporters we are providing a final Beta driver together with the release of the AMD Radeon Software Crimson Edition. The AMD Radeon Software Crimson Edition Beta driver includes the redesigned user interface as well as some enhanced features. More information can be found in the AMD Radeon Software Crimson Edition 16.2.1 for Non GCN Products Release Notes. This driver is provided "as is" and will not be supported with further updates, upgrades or bug fixes.
