我最近在系统上安装了 MiKTeX。它运行良好，但在我更新它之后，它无法正常工作并显示以下消息：
Sorry, but "MiKTeX Configuration Utility" did not succeed.
The log file hopefully contains the information to get MiKTeX going again:
C:/Users/user/AppData/Local/MiKTeX/2.9/miktex/log/initexmf.log
You may want to visit the MiKTeX project page (http://miktex.org), if you
need help.
Sorry, but D:\Program Files\MiKTeX 2.9\miktex\bin\x64\texify.exe did not succeed.

我已经卸载并重新安装它，但问题仍然存在。此消息与 MiKTeX 无法排版 但 Ulrike Fischer 的解决方案不起作用。
更新成功，完成，然后我重新启动了计算机。日志文件是：

即使我使用 pdflatex 运行，也会出现同样的错误。
