WPF窗口抛出在启动时TypeInitializationException(WPF window

我有一个Excel加载项与几个丝带，一个色带设置窗口。当它被点击，自定义窗口会显示出来。然而，没有什么点击时显示出来。我看到在日志文件中的下列情况除外。是什么原因导致这个问题以及如何解决它？非常感谢

~~从您发布的错误堆栈来看，似乎你的设置窗口中可能有它的链接。~~ ~~不幸的是，链接中有一个无效的URL，这将导致窗口创建失败。~~

编辑：你的代码和错误消息说完看着更加紧密，很明显，我一直在寻找在错误的区域。某些搜索打开了一个错误的WPF 。

短版本：WINDIR环境变量可以在目标计算机，这将导致字体subsytem打破上设置不正确。解决方法是通过添加类似以下的启动修复环境变量，无论是在目标机器的注册表，或代码：

Environment.SetEnvironmentVariable("windir", Environment.GetEnvironmentVariable("SystemRoot"));

我们有几个人遇到此问题。描述的解决方案在这里（由PATH大于2048个字符）解决了这个问题。

Answer 3:

我很担心，上述建议的声明可能是在与过多或过少的权限运行的代码有问题。当然，我的应用我的工作站上运行我的管理员有这个电话转给Environment.SetEnvironmentVariable（“WINDIR”，Environment.GetEnvironmentVariable（“SYSTEMROOT”））没有问题;

但我不知道SetEnvironmentVariable方法实际上将在锁定的OS工作。有没有人一）尝试这是真的和B）试图在低特权环境>

另外，我看到在应用程序启动时有些古怪我安装使用该调用应用程序后，一旦运行它。所有其他应用程序不再能看到WINDIR，未扩展到C：\ Windows操作系统。我要遍历整个安装和不到位运行，查看是否不TypeInvocation例外复出如果还是不行，在OS WINDIR变量是否保持不变。

更新：

我已经证实，不良行为我注意到的是，由于没有指定SetEnvironment调用的目标。使用下面的我的问题似乎有所缓解：

System.Environment.SetEnvironmentVariable("windir", System.Environment.GetEnvironmentVariable("SystemRoot"), EnvironmentVariableTarget.User);

当我没有设定目标，很奇怪的事情发生在我的Windows会话要求我要么注销和登录，甚至重新启动。因此，除非这种变化是真的要在机器或工艺水平，不承担与默认的幸福结果
