    The error pop-up related to dwgcnv.dll when trying to insert a CAD drawing in Visio may indicate a problem with the CAD file or an issue with the Visio installation itself. Here are some steps you can take to troubleshoot this issue:

    1. Check for Updates: Ensure that your Visio application is updated to the latest version, as updates may fix bugs related to file compatibility.
    2. Repair Visio: You can try repairing your Visio installation through the Control Panel. Go to Programs and Features, select Microsoft Office, and choose the Repair option.
    3. Re-register the DLL: If the dwgcnv.dll file is corrupted or not registered correctly, you can try re-registering it. Open Command Prompt as an administrator and run the command: regsvr32 dwgcnv.dll.
    4. Check File Compatibility: Ensure that the CAD drawing you are trying to insert is compatible with the version of Visio you are using. Sometimes, older or newer CAD file formats may not be supported.
    5. Safe Mode: Start Visio in Safe Mode and try to insert the CAD drawing again. This can help determine if the issue is related to add-ins or other settings.

    If these steps do not resolve the issue, consider reaching out to Microsoft Support for further assistance.

    Dear 伟伟 郭

    Thank you for reaching out and sharing your concern in the Q&A forum.

    Based on the information provided and my testing in a controlled environment using Visio LTSC Professional 2024, the Insert >> CAD Drawing feature functions normally with a standard DWG file.

    点击插入“CAD绘图”，就出现这个dwgcnv.dll错误弹窗，这个跟visio版本没关系吧？
    我目前使用的visio版本是2021专业版
    .DWG格式文件是2022版本，

    我的系统是WIN11，版本号24H2
