I have an Asrock Z97 Extreme6. Windows 10 Pro Technical Preview build 10049 works fine, this OS is much better than Windows 8.1 even at this stage. I have a problem though. I can't install any Intel RST for WIndows 8.1 (from Intel's site or from Asrock's site downloaded). I get the message that "microsoft NET framework 4.5" must be installed, which is already present in WIndows 10 because I tried to install it and received this message from the installer. Asrock's supports says that from Version 13.1.0.1058, is Net framework 4.5 required, which is in WIndows 10 present. I tried with an older driver than this and I got the message "platform not supported. Latest Version from Intel's site doesn't work as well. Any recommendations?
