【问题描述】:
我在 .NET 4.0 中编写了一个 WPF 应用程序。
我已在以下操作系统上安装并成功运行该应用程序:
- Windows XP SP2
- 远景
- 窗口 7(32 位)
- Windows 7(64 位)
在装有 Windows XP SP3 的机器上安装应用程序后,应用程序无法启动。我检查了事件查看器的应用程序日志,发现如下错误:
Application: ApplicationName.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.IO.FileFormatException

所以我猜测它与我在我的一个窗口中的一张图像有关,但不确定是什么;)
有没有人见过这个异常并有解决办法?
注意:如果这是相关的,我的安装程序会在必要时将 WIC 和完整的 .NET Framework 4.0 加载到目标机器上。
【问题讨论】:
-
您是否 100% 确定目标计算机具有您所针对的 .NET Framework 的最新服务包?
-
我这里没有机器,但除非我弄错了,.Net Framework 抛出了异常。错误日志的第二行显示“Framework Version: v4.0.30319”,所以我假设是安装的版本。

如果它与字体问题有关,您可能需要查看此链接:forums.silverlight.net/forums/p/176008/396460.aspx

您可以通过使用 sysinternals procmon 工具监控它正在访问的文件来定位它有问题的图像。
