安装.NET Framework Update后，CompositeFontParser失败 [英] CompositeFontParser Fail after installing .NET Framework Update

问题描述

Hello all，

Hello all,

使用Windows 7调用Fonts.SystemFontFamilies（System.Windows.Media.Fonts）时，我的客户端程序（C＃）中遇到异常system：

I have encountered an exception in our client program (C#) when calling Fonts.SystemFontFamilies (System.Windows.Media.Fonts) using a Windows 7 system:

- > System.IO.FileFormatException：在FontFamilyCollection中找不到与当前操作系统或更高版本匹配的FontFamily元素：Windows7SP1

-> System.IO.FileFormatException: No FontFamily element found in FontFamilyCollection that matches current OS or greater: Windows7SP1

使用Windows 10时，不会发生此问题。此外，回滚Windows 7系统上的最新安全更新修复了该错误，因此经过一些调查后，我认为连接到该异常的最可能的包是KB4055532，其中
是.NET 4.7.1安全性1月9日发布的Windows 7 / Server 2008更新。

Using Windows 10, this problem does not occur. Also, rolling back the latest security updates on the Windows 7 systems fixes that error, so after some investigation, I think the most probable package that is connected to that exception is KB4055532, which is a .NET 4.7.1 security update for Windows 7 / Server 2008 released on January 9th.

这可能是上述安全更新中的错误吗？

Could that be a bug in the mentioned security update?

亲切的问候，

Hallo Frank！

Hallo Frank!

我可以或多或少地确认您的观察结果！

I can more or less confirm your observation!

安装KB4055532后，Windows Powershell 5.1 ISE无法启动，因为它崩溃了  ; System.IO.FileFormatException也是如此。这是在Windows 7 SP1上安装了所有重要更新。

卸载此更新后，可以毫无问题地启动Powershell 5.1 ISE。

我遇到同样的问题昨天上班的8台电脑和家里的个人电脑。



亲切的问候，

After installing KB4055532 Windows Powershell 5.1 ISE cannot be started as it crashes with System.IO.FileFormatException too. This is on Windows 7 SP1 with all important updates installed.
When this update is uninstalled, Powershell 5.1 ISE can be started without problems.
I had this same problem on about 8 computers yesterday at work and at my personal computer at home.

Kind regards,
