我在控制面板“添加和删除程序”栏中双击始终打不开，出现一不明对话框，截图如上

刚才上Baidu搜了下,得到这个答案,蝈蝈试一下:
在widnows xp下，运行添加删除程序时，有时会遇到creation failed at line472 or 521错误，具体来讲，在SP1下提示 Value creation failed at line 472；在SP2下提示 Value creation failed at line 521。这个故障一般是由于windows 主题造成的。
解决方法：
控制面板－外观和主题－显示－主题，把主题设置为windows xp即可。
When use Add or Remove Programs in Windows XP, you receive ';parser message value creation failed at line'; 472 or 521?
In Windows XP, when you use Control Panel to run the Add or Remove Programs applet, you receive:
Service Pack 1
Parser Message: Value creation failed at line 472
Service Pack 2
Parser Message: Value creation failed at line 521
This behavior is generally the result of a theme problem.
To resolve this issue:
1. Open Control Panel.
2. Open the Display applet.
3. Select the Themes tab.
4. In the Theme drop-down box, select Windows XP.
5. Press Apply and OK.

啊，好了，完全正确，谢了
