I tried installing AMD APP 2.6 again and it just does the same thing, it deletes stuff and makes the miners GUI/Phoenix display that i have no OpenCL divices, i have Intel OpenCL Installed too by the way. All the Motherboard chipset drivers installed, i have no idea whats wrong here, my AMD Sempron rig is acting the same way it's not installing 2.6 (The installer literally installs for 2-3 seconds and says it dones) after a restart same message "No supported devices, after i "try" to install 2.6 i have to completly uninstall my drivers and reinstall everything all over again because 2.1 will not install it's core files.
afaik, intel opencl is only for intel cpu tasks; might work for other hardware (amd cpu, amd gpu) but would likely be highly unpotimal and slow. same for amd app, its aimed for amd gpus, and likely is much slower for any other hardware. this is mostly educated guessing though
