This Blu-ray Disc needs a library for AACS decoding
There are two scenarios that can trigger this error. They are-
- Blu-ray disks are being protected by AACS and BD+ technologies.

The fix for both of them requires the same steps to be undertaken.
First of all, you need to check the architecture of Windows and VLC is installed on your computer. It will be helpful.

Now, you need to copy the first Keys Database file that you downloaded to the AppData Folder.
For that, hit the WINKEY + R button combination on your keyboard.
Now, type in %APPDATA%\ and hit Enter.
Create a folder in the location opened in the File Explorer and name it as aacs.
Paste the KEYDB.cfg file inside this folder.
Now, get the AACS Dynamic File that you downloaded.
