@adriano_lapel Thanks for your question - as this seems to be an in-product excel issue (I think how to configure autoload for Workspace Excel add-in or similar) - I have opened case 13343143 on your behalf and someone will reach out to you shortly. Please let us know how you get on.

below sample code, you need to launch excel process and use marshaling, excel interop does not load correctly excel addin

var proc = Process.Start("excel.exe");
Microsoft.Office.Interop.Excel.Application oExcelApp = null;
while (oExcelApp == null)
{
    try
    {
        oExcelApp = (Microsoft.Office.Interop.Excel.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application");
    }
    catch
    {
        System.Threading.Thread.Sleep(1000);
    }
}
excelApp.Workbooks.Open(...);
