System.IO.FileLoadException。无法加载辅助功能，版本=2.0.0.0

Question

我最近刚刚遇到这个问题，这可能是由于我在机器上安装的某些东西造成的。但我不记得了。每隔一段时间，我就会收到一个 Microsoft .NET Framework 消息框在我的计算机上弹出，它告诉我：

“您的应用程序中的组件发生了未处理的异常。如果您单击“继续”，应用程序将忽略此错误并尝试继续。

无法加载文件或程序集“辅助功能， 版本=2.0.0.0，文化=中立， PublicKeyToken=b03f5f7f11d50a3a' 或其之一 依赖关系。给定的程序集名称或代码库”

我尝试重新安装 .net 4.0 框架。我找不到 .net 2.0 框架下载来重新安装它。我尝试使用 gacutil /uf 可访问性强制卸载该 dll，但这不起作用。我还检查了 Accessibility dll 的安装位置并将其与其他计算机进行了比较，一切都相同，包括 global.config 和 web.config。

此异常不仅发生在我的计算机上的一个进程中，因为它是一个进程。我的 GAC 出现问题，任何使用此程序集的应用程序都会引发相同的异常，

我打开了 Fusion 的绑定日志记录，详细信息告诉我：

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box."

任何帮助将不胜感激。

Answer 1

您的 Accessibility.dll 很可能已损坏。即使作为管理员，您也无法删除该文件。

您必须进入安全设置并将所有者从 TrustedInstaller 更改为其他用户，并授予自己对该文件的权限。完成后，从工作计算机获取 Accessibility.dll 并替换损坏的版本。

据我猜测，Microsoft 的安装程序损坏了 DLL，因为没有用户有权编辑/删除/替换 TrustedInstaller 拥有的文件。
