Symptoms

If QT7 is installed, CALD2 displays an error message when you open the CALD2 application. If you click Cancel then the program later displays a new error message when you click on a sound icon, and the program does not play the sound file.

如果在你的操作系统上安装了QT7，当你打开CALD2程序时会显示一个错误信息，当你点击这个错误信息窗口上的取消按钮后会出现第二个的错误信息，关掉第二个错误信息窗口后语音文件不会正常播放。

Solution

You can fix the problem in the following way.

你可以通过以下方法解决这个问题

• First of all, create a new folder
  在你的硬盘上创建一个新的文件夹
• Download this file and save it into your new folder
  下载这个文件保存到你新建的文件夹中
• Extract or unzip the patch into this folder. You can do this by right-clicking on it and selecting Extract here
  
  解压这个下载的压缩文件到你新建的文件夹。（你可以右键点击这个压缩文件，选择弹出菜单中的解压到当前文件夹）
• Close CALD2
  关闭CALD2程序
• Go into My computer
  双击我的电脑
• Go into your hard drive, usually C drive.
  选择硬盘，通常是选择本地磁盘C
• Open the folder called program files
  打开目录program files
• Open the Cambridge folder and/or cald2 folder
  打开Cambridge目录或者cald2目录（取决于你安装在那个目录）
• Open the plugins folder
  打开plugins目录
• Remove all files in the plugin directory — i.e. the files:
  删除plugin目录里的所有文件 - 例如下面的文件
  • npnul32.dll
  • npqtplugin2.dll
  • npqtplugin3.dll
  • npqtplugin4.dll
  • npqtplugin5.dll
  • npqtplugin6.dll
  • npqtplugin7.dll
  • npqtplugin.dll
  • QuickTimePlugin. class
• Copy the files that you unzipped earlier from our patch into the now empty plugin folder. After this operation the plugin directory should contain the following files:
  将之前从网上下载的压缩文件中解压出来的文件拷贝到这个空的plugin目录中，完成后会有以下文件
  • npnul32.dll
  • npqtplugin2.dll
  • npqtplugin.dll
  • QuickTimePlugin. class

When you have made this change, CALD2 will open without any error message and you can play sound without receiving an error message.

当你完成上面的操作后CALD2程序就可以正常的打开了。
