Solution for Windows
Step 1. Download VLC Media Player
Download the latest version of VLC on https://www.videolan.org/ and install it on your Windows. The VLC media player must be over version 3.0 to play encrypted Blu-ray discs.
Note: It would be better to note down the installation path, especially if you don’t have VLC installed in the default path. For example, I have installed VLC 64 bit on my 64 bit Windows computer with the default installation path C:Program FilesVideoLANVLC. That is the “VLC directory”. In the next steps, I need to put some files correctly inside.
Step 2. Download Keys Database and AACS Dynamic Library
Go to https://vlc-bluray.whoknowsmy.name/ to download two files: keys database and AACS dynamic library. Please note that the AACS dynamic library is available in two versions, one for VLC 32 bit and one for VLC 64 bit.
For convenience, here are the direct download links.
Download keys database (VLC 64 & 32 bit): https://vlc-bluray.whoknowsmy.name/files/KEYDB.cfg
Download AACS dynamic library (VLC 32 bit): https://vlc-bluray.whoknowsmy.name/files/win32/libaacs.dll

Step 3. Place the Keys Database File
Enter C:ProgramData in the File Explorer address bar, and then create new folder names “aacs” by yourself. After done, put the downloaded keys database file (KEYDB.cfg) in this folder. The file path would be C:ProgramDataaacs.
Step 4. Place the AACS Dynamic Library File
Put the AACS dynamic library file (libaacs.dll) in your VLC directory. The default path would be C:Program FilesVideoLANVLC for Windows 64 bit.
