TUSBAudio driver preinstallation failed to install

Hello,

This error is occurring because of Windows’s driver signature checking. This setting is applied harder than x86 OS. So, what you’ve to do is to disable this option and then install the driver.

1. Press “Ctrl + X”.

2. From the pop-up menu, select “Command Prompt(admin)”.

3. When the console window comes, type and hit enter the following commands:

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

4. Now try to install your driver again.

If you have to re-enable this again, run the following commands;

bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING OFF
