我已经使用 Visual Studio 2008 编译和 .exe。在任何其他 PC 上的 w7 上，它都可以正常工作。但是在装有 XP 的 PC 上，它给了我我不明白的错误：

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

我是 .net 的新手，所以请清楚地解释我该怎么做谢谢。

您是否要实例化 XP 机器上未安装的字体？也许一个默认安装在 Windows 7 但不是 XP 的？
