Hello Amit,

Please check if the issue exists with Add-in Express 8.9; see https://www.add-in-express.com/downloads/adxnet.php. Make sure that your add-in uses AddinExpress.XL.2005.dll installed on your machine: the information you provide shows your add-in has a reference that points to AddinExpress.XL.2005.dll version 8.2.4371, not 8.7.4430.

This issue is still coming after upgrading to newer adx.

My adx dll version is 9.1 and I'm using addinxpress 8.2.4371.

What are the next steps.

Hello Amit,

Please make sure that all Add-in Express assemblies in your project as well as adxloader.dll and adxregistrator.exe that your installer deploys are of the same version. Also, always provide a full log with the call stack: this helps immensely.

Hello Amit,

We assume that you have different versions on AddinExpress.MSO.2005 and AddinExpress.XL.2005 assemblies in your project.

If this isn't the case, please provide us with a project that reproduces the issue.

Did you ever switch your add-in from per user to permachine or back?

Hi,

We are using latest 9.2 build and confirmed that AddinExpress.MSO.2005 and AddinExpress.XL.2005 are latest.
We haven't switched addin from per user to permachine or back. It has been always permachine.

These are the steps -
1.Install addin
2. Open file f1.
3. Open file f2
4. Close f2
5. close f1 -> error

---- Stack Trace ----
System.Runtime.InteropServices.ComTypes.IConnectionPoint.Unadvise(dwCookie As Int32)
AddinExpress.XL.2005.DLL: N 00000 (0x0) JIT
AddinExpress.XL.ConnectionPointConnector.Disconnect()
AddinExpress.XL.2005.DLL: N 0015 (0xF) IL

AddinExpress.XL.ADXExcelTaskPanesManager.FinalizeClass()
AddinExpress.XL.2005.DLL: N 0191 (0xBF) IL

Please note that we can also not reproduce the issue. It is coming on customer machine and all machine with excel 2013 has same type of error. We have also verified that there is no other addin in the environment.

What I am looking for is a solution for handling these type of error. It seems that issue comes after addin shutdown event and it is not captured in the OnError event.
Do you think that it is something related to task manager dispose? if yes, then can you handle this error internally?

We have also created a dummy project where issue is reproducible. It is per user.

Code below

public partial class AddinModule : AddinExpress.MSO.ADXAddinModule
{
private ADXExcelTaskPanesManager adxExcelTaskPanesManager;

private ADXRibbonTab adxRibbonTab;
private ADXRibbonGroup adxRibbonGroup;

InitializeComponent();

Hello Amit,

Sorry for the delay; we were on holidays and it appeared impossible to find a specialist who could respond.

In the AddTaskPane method which is called from the constructor of the add-in module, you perform these calls:

ADXExcelTaskPane managedWorkbooktpinstance = mytpitem.CreateTaskPaneInstance();
managedWorkbooktpinstance.Show();

Comment out these code lines. You shouldn't create task pane instances as they are created by the forms manager itself.

If you need to control the instances, you can use 1) the ADXOlFormsManager.ADXBeforeFormInstanceCreate and/or 2) ADXOlForm.ADXBeforeFormShow (in this event, you can prevent the form instance from showing by setting ADXOlForm.Visible=false).
