Windows Cannot Verify Driver Signature (on signed driver)

In rare cases, and especially with Windows 7 x64, we got the installation issue where virtual audio driver are installed but disabled because a digital signature problem. Even if forcing the Setup program to run in administrator mode.

The message given in the Device Manager for the disabled Driver is:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)" in device status

The reason we found is a problem of Windows Update (preventing to admit recently signed drivers).

1- You may de-install this drivers and REBOOT.
2- You may update WINDOWS 7 with Control Panel / Windows Update
3- If your Windows Update does not work (stuck), you may follow this solution: ... bleshooter

The goal is to update WINDOWS to let it understand the driver signature.

in 2021 the SHA-1 Code Signing algorithm will be replaced by the SHA-2 algorithm only.
(Dual Code Signing process could not be possible anymore... ).

Windows 7 Update should contain the SHA-256 Certificates support anyway: ... a4cde8e64f
