My Radeon 7570 that comes with my hp envy h8-1409 is not being detected by CGminer (Litecoins)
It's a bit janky, but I've finally found a solution to this situation.


Download this driver sp57510.exe
Attempt to run the installer - it will eventually get to a point and then fail. When it gets to the point that it tells you 'Unsupported System' with an OK button, don't press OK just yet. Open /appdata/local/temp. In there, find the most recently created folder. It's contents should look like this:





Go into the /src/ folder, and you should find an ATI Setup.exe. Run that. My driver was up to date, but it did add the AMD APP SDK stuff and now CPU-Z reports that OpenCL is available, and cgminer is chugging away.
