Disabling a toolbar button in Embedded Designer Controls throws Exception -

Reference:

SAP Note 1220368 - How to disable/enable the toolbar buttons on the Embeddable Designer control

We are using Embedded Crystal Designer Control in our C# .NET Windows Form. To disable the "Insert Picture" toolbar button on the Crystal Designer Control, used the following code:

CRDesignerCtrl1.ShowToolbarButton(CRDESIGNERCTRLLib11_5.CRToolbarButtonId.crTBInsertPicture, false);

When I run our application and go to the form having the Embedded Crystal Designer Control, I am getting the following Exception:

Source: Interop.CRDESIGNERCTRLLib11_5

Message: Error HRESULT E_FAIL has been returned from a call to a COM component.

Does anyone have any suggestions to rectify this problem?

Thanks & Regards,
