I have tried to uninstall B450 chipset 1.7.29.0115 by using the normal windows uninstall, the AMD cleanup utility, and deleting all AMD folders and any chipset file I could find in the system32 folder. I have also tried installing new chipsets on top of 1.7.29.0115. No matter what I do, the driver versions are all from 1.7.29.0115 and no matter how many times the system tells me that everything was uninstalled successfully, 1.7.29.0115 is still listed in the installed apps area and if I try to uninstall more than once, the only thing listed is something called "AMD Driver." It will say it uninstalls successfully, but it's just an endless loop.
I am now stuck with 1.7.29.0115 and can never update or change unless I wipe the hard drive and re-install windows it appears. Thanks AMD and ASUS, you guys rock!
