Dear all,

i get on Disks the following message from Makemkv:

"This disc requires Java runtime (JRE), but none was found. Certain functions will fail, please install Java. See http://www.makemkv.com/bdjava/ for details."

I have Java RE installed but it seems, that its not recognized.

Does anybody know how to fix this?

rgds, Holger

I assume that you are using Windows.

Open a "Cmd Window" (the Terminal Window)

Type "java -version" ... what ist shown?

The Java Version i use is

jdk-14.0.1_windows-x64_bin

That's not what I ask. So please ...

Provide a full Debug log and did you specify in the MakeMKV "Protection" settings anything in the "Custom Java executable location"?

I made the same experience. The solution for me was to install JRE8 besides JDK14.

Yes, the OP also has a JDK (Development Kit), don't know if a JRE (Runtime Evironment) is included in this version. JDK are only needed for developers, but not for executing already build java code.

I use the Orcale JRE version from https://www.java.com/ Simply install it, no special things needs to specify in MakeMKV, it's automaticaly detected.

Yes, the JDK contains the JRE. Personally, I need the full JDK because of other purposes. At last I had successfully blu-ray playback with menus after the additional installation of the actual JDK8 only. After that I stopped further investigations.

yes, right, from my side the item can be closed. i also recognized that i installed the developer kit in stead of the runtime environment. Now i put JRE on and its fine
