You have no secondary Graphics Card right? Assuming the 7500 in that section refers to the APU's GPU.
Try this driver: http://support.amd.com/en-us/kb-articles/Pages/latest-catalyst-windows-beta.aspx and run it as administrator after first removing all previous drivers first.
If that doesn't work, try your motherboards included chipset driver.
Still having issues, try running "sfc /scannow" in an elevated command prompt and then try to install again.
