I installed VLC on my new Windows 10 64-bit OS machine via the Windows App Store. I want to add Blu Ray support and found https://vlc-bluray.whoknowsmy.name/ telling me how to do it -- except for app store installs, that is. Apparently app store installs don't go to "c:\Program Files" and don't have an executable named "vlc.exe". Instead, it hides itself in a protected directory, "c:\Program Files\WindowsApps". The VLN install goes to 4 subdirectories with long names, one of which contains the executable file: "VideoLAN.VLC_3.2.1.0_x64__paz6r1rewnh0a\VLC.Universal.exe".
Fine. That only took an hour to figure out. <sigh> BTW, VLC runs fine, and is version 3.2.1.0.
I make the directory C:\ProgramData\aacs and place KEYDB.cfg in it. (Instructions don't say make the directory, but there wasn't one.)
Now I'm stuck. I don't know whether this is a 64 bit file, as the "x64" part of the long-a** directory name would indicate, or a 32-bit file, as VLC.Universal.exe would indicate. Besides that detail, I can't add anything to the directory because it is protected, even from a dos promp shell with administrator privileges.
How do I continue? And do I want the 64-bit DLL or the 32-bit DLL?
