When I use below code to start annotation during zoom meeting, annotation is not started.  
StartAnnotation function returns value 24. What do you mean by 24. There is no description for SDKError value 24 in Zoom documentation.

IAnnotationControllerDotNetWrap mAnnotationController = ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetAnnotationController();  
SDKError sDKErrorStAn = mAnnotationController.StartAnnotation(SDKViewType.SDK\_SECOND\_VIEW);

**Which Windows Meeting SDK version?**  
5.9

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Join meeting using windows sdk function from downloaded c# windows desktop code.
2. Write the above code.

- OS: Windows 10

PLease guide to write the code to start annotation .

Hi @arvind.sonar,

Based on the values in the `SDKError` enum, this value maps to `SDKERR_MEETING_ANNOTATION_IS_OFF`. This means that annotations are not currently enabled. To enable annotation, you can follow the steps listed in [this article](https://support.zoom.us/hc/en-us/articles/4409894568845-Enabling-or-disabling-annotation-tools-for-meetings). 🙂

Thanks!

Hi @arvind.sonar,

Can you please confirm what you are seeing returned from [`isAnnoataionDisable`](https://marketplacefront.zoom.us/sdk/meeting/windows/class_i_annotation_controller.html#ae625b9c86c79e202900851f4f08533b8)? If this value is true, that means that you cannot annotate in the current meeting.

Thanks!
