Hi, Jason. I think that I mistyped. v0.9.23 was the corrected version as best I recall.

Hi Robert, Sorry to bother you with such a basic problem, but I've run out of internet search fixes on this one. Hopefully you can point me to a quick solution. I have a new Intel NUC running Windows 11. I successfully downloaded the latest version of Java but when attempting to check the version in the Terminal Prompt window it says it is not present, despite a successful install. Tried pointing the JRE Finder Java Runtime Environment s to the downloaded LDCT folder, but it does not see the file...

Hi Robert, Your rebuild of 2022-09-29 works nice in my windows 10 64 and in my linux Mint 20.3 64bit. Both OS run your file without bugs or errors. Thank you very much and have a nice day. https://sourceforge.net/p/ldct/tickets/10/#740c this is my ticket.

I rebuilt the LDCT.jar file which should fix the problem. Please download the LDCT v0.9.3.zip file and give it a try. If you have further problems, please open a new ticket. Sorry for the inconvenience and thanks for using LDCT.

Sorry that you're having problems, Jorge. I had to replace my system earlier this year and don't have the Java development environment configured yet so I can't research the problem immediately. I can confirm that I'm having the same problem on Windows 11 64-bit with Java 1.7. If you need a quick solution and have a Java development environment, the source code is posted in this project. Otherwise, I will post an update as soon as I can. Thanks.

Hi, Paolo. Sadly, my Linux box isn't currently set up so I can't easily investigate. I haven't messed with the code in some years now so I don't have any real insights. Since this problem hasn't been reported before, I think that you're probably right about it being a configuration issue but not sure what to suggest. I'm currently in the middle of another project so I cannot immediately research. Sorry to leave you hanging. If you have the skills, you could, of course, load the source, compile, and...

Hi, Nicolas. Well, you're asking about support for Java 6. LDCT requires Java version 7 or later as detailed in the readme text on the Files tab of this SourceForge project. I don't support Java 6 because the code uses features not in that version of Java. I'm not a Mac guy but Java 7 appears to be available for OS X 10.7.3 and above. If you are unable to upgrade your OS X, then you can download all of the Java sources from this project and backport them to Java 6. I don't think this will be easy...
