It's been very hard to run this software on Windows 10.
First, I tried what I thought to be the default installer for Windows (0.92). It succesfully runs but as shown in this issue (https://sourceforge.net/p/protobufeditor/tickets/1/), hangs before ending.
In that same issue, a comment from the developer advise to install version 0.98.2, but that exe won't launch as it relies on Java 6, not installed in my computer. I guess it's not embedded in the exe as in 0.92. Anyway, I setup Java 6 in my computer and now the installer launches and won't freeze.
After completion, the installer created a shortcut in my computer, but the program won't start anyway. Examing the shortcut, everything looks fine "<path_to_binary>\javaw.exe" -jar "<path_to_program>\RunProtoBufEditor.jar" so I open a terminal and run the command. Seems like Java cannot find the main class in RunProtoBufEditor.jar. Indeed, if we examine the jar file, the name of the class is RunProtoBufferEditor instead of RunProtoBufEditor, so there's the mismatch with the jar file.</path_to_program></path_to_binary>
Now, I run java -cp RunProtoBufEditor.jar net.sf.RecordEditor.RunProtoBufferEditor, but another exception is thrown. Now the interpreter does not seem to find the class FileVisitor. Browsing the docs, https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/FileVisitor.html, it seems this classs was added in Java 7.
So now, I install Java 7, and finally I'm able to sucessfully run the program.
