更新Matlab2021a到update6时遇到错误，目前无法启动matlab。尝试安装离线更新，但是无法下载到离线安装包。
打算重新安装，卸载时又遇到错误： \MATLAB\R2021a\help\simulink\helpsearch\segments_u (系统找不到指定的文件。)
请问该怎么办？谢谢~~

一样，请问你最后怎么弄的啊，是否只能完全删除文件，重新安装?

Hello Charles,
As per my understanding, encountered an error when updating Matlab2021a to update6, currently unable to start MATLAB.
Please note that here are a few steps you can try to resolve the problem:
  • Restart your computer: Sometimes, a simple restart can help resolve temporary issues with the installation or update process.
  • Repair MATLAB installation: Instead of uninstalling and reinstalling, you can try repairing the MATLAB installation. To do this, go to the Control Panel (Windows) or System Preferences (Mac), find the MATLAB installation, and select the option to repair it.
  • Clear temporary files: Delete any temporary files related to MATLAB. You can do this by going to the MATLAB installation folder (usually located in `C:\Program Files\MATLAB\R2021a` on Windows) and deleting any temporary files or folders.
  • Manually uninstall MATLAB: If the repair option doesn't work, you can try manually uninstalling MATLAB. This involves deleting the MATLAB installation folder and any associated files or folders. Make sure to back up any important MATLAB files before doing this.
  • Reinstall MATLAB: After completing the above steps, you can try reinstalling MATLAB 2021a from scratch. Make sure to download the installer from the official MathWorks website and follow the installation instructions carefully.
You can refer the following article for more details:

I hope it helps.
