i have ati graphics driver version12.3. i downloaded the 12.4 version and removed the old 12.3 through control panel and restarted my pc. now installed the12.4 version installation completed successfully (I also checked the log everything was success including display driver). but still in my vision engine control center it is showing 12.3 not 12.4. same as in case of gpuz http://gpuz.techpowerup.com/12/05/17/6ut.png
It is a very common problem right now. All the other forums have threads on this topic right now. Stick with 12.3. I set up a RAID 0 and did a fresh install of windows and was able to get 12.4 to install but then I had a Problem with Masseffect3 so I thought I would try a different driver version to see if that was my issue. Since then, I have not been able to reinstall 12.4. I have tried driver sweeper and it still won't install.
