错误似乎无处不在.有什么想法吗?
The error just seems to have come out of no where. Any ideas?

推荐答案
我的猜测是，对"EMS.Controls.Dictionary.StatusBarControl"控件的引用是应该在用户GAC中安装的库的一部分.确保您没有缺少应用程序先决条件.
My guess would be that the reference "EMS.Controls.Dictionary.StatusBarControl" control is part of a library that should be installed in the users GAC. Make sure you're not missing an application prerequisite.
