错误提醒：
异常信息: System.NullReferenceException 在 MS.Internal.FontCache.FontFaceLayoutInfo+IntMap.TryGetValue(Int32, UInt16 ByRef)

修复过程

首先重新安装了下net 4.5.2的环境，安装后运行程序仍然报错。然后又在win7个性化设置里面设置了字体，在其他电脑拷贝了宋体字体覆盖到问题电脑，使用Windows Aero (Tahoma Font).exe主题修改 这些方法都不行。仍然报错…

最终解决办法

修复win7注册表：使用系统自带字体的注册表对问题机器进行注册表合并。然后运行软件，完美解决。注册表如下：

Windows Registry Editor Version 5.00

;Restores default system font setting (to Segoe UI) in Windows 7

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
“Segoe UI (TrueType)”=“segoeui.ttf”
“Segoe UI Bold (TrueType)”=“segoeuib.ttf”
“Segoe UI Bold Italic (TrueType)”=“segoeuiz.ttf”
“Segoe UI Italic (TrueType)”=“segoeuii.ttf”
“Segoe UI Light (TrueType)”=“segoeuil.ttf”
“Segoe UI Semibold (TrueType)”=“seguisb.ttf”
“Segoe UI Symbol (TrueType)”=“seguisym.ttf”

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
“Segoe UI”=-

把上面文本，保存为xxxx.reg然后进行注册表合并
