As far as I am aware AMD is still supporting all RX series GPU cards including the 500 series GPU cards as per AMD Download page for the RX 570: https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-570
The link posted by FunkZ mentions that your GPU card is not in legacy status but that AMD drivers won't be as advanced or feature rich as the newer GPU card drivers. Here is AMD response to the linked article:
The AMD Polaris and Vega graphics architectures are mature, stable and performant and don’t benefit as much from regular software tuning. Going forward, AMD is providing critical updates for Polaris- and Vega-based products via a separate driver package, including important security and functionality updates as available. The committed support is greater than for products AMD categorizes as legacy, and gamers can still enjoy their favorite games on Polaris and Vega-based products.
From the above link of the Latest AMD Driver "Release Notes" concerning compatibility of Operating Systems:
Compatible Operating Systems
AMD Software: Adrenalin Edition 24.1.1 is designed to support the following Microsoft® Windows® platforms. Operating System support may vary depending on your specific AMD Radeon product.
- Windows 11 version 21H2 and later
- Windows 10 64-bit version 1809 and later
One thing that is important for installing the latest AMD Driver, your Windows 10 must be fully updated via Windows Update.
So make sure you have all the latest Windows 10 Updates installed not including Drivers.
Also make sure your Windows Driver Update is "DISABLED" from updating drivers via Windows Update. Here is how to do it: elevenforum- enable-or-disable-include-drivers-with-windows-updates-in-windows-11.2232/
This will prevent Windows Update from replacing your current AMD driver with one that is incompatible.
Download DDU (Display Driver Uninstaller) and delete the AMD Driver installation folder, if created, at C:\AMD. Run DDU and when it reboots back into Windows install the full latest AMD Driver with the Internet disconnected.
NOTE: Post back the exact AMD Installation error you are getting if it fails again. Also run in a elevated Command Prompt or Powershell the following simple command line; SFC /scannow .
That command will check your Windows 10 for any corruption or missing files and repair it.
