楼主
求助！
我在使用matlab联合CST建模时出现问题：
matlab报错：Invalid character code sequence detected.
CST则弹出弹窗显示：
CST Update Manager reported the following error:License details are required to check for updates, Please specify -.license command line option.
Please manually start CST Update Manager to fix the problem and tobe able to receive the latest updates.Additional information can be found in the logfile (Patchesllog.txt).
逐步debug显示，代码运行到：
invoke(mws, ‘SetApplicationName’, ‘5GHz_Circular_Patch_Automation’);
这一句时候报错，我是用的版本是CST2025和matlabR2024a
matlab是正版的，CST是破解使用的，请问是什么问题，有大神能解决吗？![[泪]](/static/emoticons/u6cea.png)
