I'm trying to install the Realtek Audio97 sound driver from the Realtek driver download page for Windows 7.

Every time I try to run the installer I get the error message:

"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.

    Do you actually need AC97? IIRC, Realtek High Definition Audio Codec superseded AC97 and ac97 is need only for backwards compatibility. – horatio Oct 12 '12 at 19:32

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)

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON

  • Will you Type UAC into the windows search and turn it off. Try install then – Wessel Oct 12 '12 at 21:00
  • UAC was and is disabled. – Steph Oct 12 '12 at 22:21
  • It's also the home edition so I there's no gpedit.msc option either. – Steph Oct 12 '12 at 22:21
  • "testsigning on" does not allow you to load unsigned drivers. It enables loading of drivers that have been signed with a "test certificate", which anyone can get (i.e. it does not provide traceability of authorship). – Jamie Hanrahan Mar 4 '17 at 19:49
