Upgrade to a newer GPU (even a used Radeon RX 400 series or GTX 900 series) for proper Windows 10 driver support. If you must use the HD 4890, stick to Windows 8.1 or Linux (where open-source radeon drivers still support it perfectly).

Run the installer. It will extract the installation files to C:\AMD\Support\... and then launch the setup wizard.

If you want to try the last official driver (Catalyst 15.7.1) on Windows 10 64-bit:

The ATI Radeon HD 4890 was a significant improvement over its predecessor, the Radeon HD 4870, offering faster performance, improved power consumption, and new features like DirectX 10.1 support.

Search for "AMD Catalyst 13.1 Legacy Windows 8 64-bit."

Download the from the official AMD driver archive website.

If you're still using the ATI Radeon HD 4890, consider upgrading to a newer graphics card for better performance and compatibility with modern software.
