Method 1: Update Video Card driver
Support feedbacks suggest that by update the video card driver prior to installing the update resolve the problem.
Video card manufacturers often release updates to their drivers to enhance performance or fix compatibility. If you need the latest driver for your video card, visit the support section on your video card manufacturer's website for information on how to download and install the newest driver.
Method 2: Remove Daemon Tool Driver (SPTD.SYS).

Please post your results (even if you are successful at resolving the issue).
When posting, please include the following details:

You should be able to capture all of the above details via DirectX Diagnostic Tool:

The DirectX Diagnostic Tool opens.
2. In the DirectX Diagnostic Tool, click the Display tab.
The video card's name and the video card's manufacturer are listed under Device. The driver version is listed under Drivers.
Thanks!
