I have a Windows 7 64 bit laptop. I own an ATI Mobility Radeon HD 5470, when I attempted to update from V12.6 to V12.10 it only installs the HDMI/DP Audio Driver V18.104.22.16808. I have cleared my system of everything ATI related and ran a full reinstall only to see the Audio Driver and Install Manager get installed. I have found a driver that runs a full installation but its from 2010 (V8). This old driver is usable but has a very hard time running newer video games. At this point any information on this subject would be helpful, if there is a fix to this problem please let me know.
