安装不了

Hi @WZ_13640046,

Thank you for reaching out with your question.

To assist you better, could you please provide more details and context regarding your inquiry? Specifically:
 

1. What specific error message are you seeing? 
2. What operating system or device are you using for the installation? 
3. What troubleshooting steps have you already tried, and what was the result? 

Are you using the Trail version of Mathcad or the enterprise edition?

When you say you can't initiate a case, do you mean you're unable to submit a request on the support platform? Was there any message or error? 

Including screenshots can also be very helpful in understanding your process. This will enhance the likelihood of receiving valuable assistance from other Community members.

You might also find it useful to refer to the guide on how to ask a good question. 

I hope this information is helpful.

Best Regards,
