我正在尝试修改Windows注册表，以便某些音频文件扩展名的上下文菜单，以便在所述文件上启动我的应用程序。该应用程序是用Java编写的，但是使用Winrun4j包装在exe包装器中。
我一直在使用此示例How do I make context menus for my software?来尝试执行此操作。令人沮丧的是，演示为.txt文件添加了一个上下文菜单，并且可以工作，如果我破解代码并将其添加到我的应用程序中.txt文件也可以。但是，如果我只是更改代码以处理音频文件，如.mp3没有报告错误，但它不起作用，在.mp3s的上下文菜单上没有显示任何选项
代码检查特定组是否与另一个应用程序相关联，是否影响输入到注册表中的值，但音频文件和文本文件都与另一个应用程序相关联（Audio Vlc，txt，UltraEdit）所以这似乎不是问题。我确实尝试忽略这些应用程序并直接添加到Software / .mp3 / classes而不是Software / Vlc / classes中，但它没有任何区别。
这是我跑步时的输出：
