Hi,
My name is Cindy. I am sorry you are having this problem. I know it is really frustrating. I will do my best to help you with this problem.
Have you tried checking the Microsoft Store for the program.
Please click on the Microsoft Store Icon.
This icon is White and looks like a shopping bag.
It has four different colored blocks like the Microsoft logo.
It can be found on the taskbar or in the Start.
The start icon is on the left side and is four boxes of blue.
Once in the Microsoft Store, click on the My Library or the Library. This will open all of your apps. You should see the Dolby access. You can click on it to download it to your computer.
Please let me know if you have any questions.
Cindy
