A4Tech Webcam has not passed the Windows Logo Testing

I am trying to install A4 Tech Webcam. Once I begin to install the software, I get a message that indicates a mistake that this can be not passed the Windows emblem testing.
It recommends me to prevent the installation and contact the software vendor. My question is if I can use this software securely?

Software Installation Error:

Continuing your installation of this software may impair or destabilize the correct operation of your system either immediately or in the future. Microsoft strongly recommends that you stop this installation now and contact the software vendor for software that has passed Windows Logo testing.
