title: UiPath StudioX - Outlook Desktop Application COM add-in error
body: <p>UiPath Community,
  I am unable to utilize any of my Outlook automations using UiPath StudioX. Whenever I run the sequence, I encounter the following error message: &quot;RemoteException wrapping System.Reflection.TargetInvocationException: Property accessor ‘Account’ on object ‘UiPath.Mail.Activities.Business.OutlookApplicationCard’ threw the following exception:‘Unable to cast COM object of type ‘Microsoft.Office.Interop.Outlook.ApplicationClass’ to interface type ‘Microsoft.Office.Interop.Outlook._Application’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{00063001-0000-0000-C000-000000000046}’ failed due to the following error: Interface not registered (Exception from HRESULT: 0x80040155).’ —&gt; RemoteException wrapping System.InvalidCastException: Unable to cast COM object of type ‘Microsoft.Office.Interop.Outlook.ApplicationClass’ to interface type ‘Microsoft.Office.Interop.Outlook._Application’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{00063001-0000-0000-C000-000000000046}’ failed due to the following error: Interface not registered (Exception from HRESULT: 0x80040155). &quot;</p>
  <p>I would highly appreciate your help and explanation to resolve the problem.</p>
