本人电脑环境win10 64位，已安装matlab2017b，现在同时安装最新版matlab2021b，启动后弹出如下警告，simulink产品无法正常运行。请问该如何解决。

警告: 在 matlabrc 中执行启动失败。

这表明您的 MATLAB 设置中可能存在严重问题，应尽快解决。检测到的错误为:

Hi shaolong,

This error message may indicate an issue with your 'startup.m' file. This file is located in $MATLAB\toolbox\local (where $MATLAB is the MATLAB installation directory). Check if any recent changes were made to this file that could be causing the error. The error message may also indicate the existence of a duplicate 'startup.m' file.

Execute the following command to locate all 'startup.m' files:

>> which -all startup.m

Rename any incorrect file, and restart MATLAB. Check to see if the issue persists. If the issue persists, temporarily rename your 'startup.m' file and restart MATLAB. Again, check to see if the warning message is still generated.
