Here is how you go about updating to a new version of Adrenalin:
1) Download DDU (Display Driver Uninstaller)
2) Download the newest Adrenalin Software
3) Disconnect from the Internet
4) Boot into Safe Mode (I do it via MSCONFIG)
5) Run DDU to get rid of the existing Adrenalin Software
6) Reboot
7) Reboot back into normal Windows mode
Install latest AMD Adrenalin Software
9) After a successful installation, reconnect to the Internet
It used to be that you could choose "Factory Reset" from the "Additional Options" screen when you first start the installation; however, due to Micro$haft launching its own updates whenever it **bleep** well pleases, it would corrupt Windows when the Windows update coincided with a Factory Reset installation of the Adrenalin Software.
For this reason AMD no longer gives you that option.
