I'm trying to install the Realtek Audio97 sound driver from the Realtek driver download page for Windows 7 and every time I try to run the installer I get the "Windows Can't verify the publisher of this driver". No matter how many times I select "Install this driver anyway", it just keeps coming back in a forever loop to that same popup window.
Have you run the installation as Administrator?
If yes try this.
Go to start type CMD prompt then copy and paste this (this will disable digital driver signing authentication)
