https://community.blueprism.com/t5/Product-Forum/SAP-Analysis-for-Excel/m-p/62720#M15775 Ok, so i have a code than can activate or deactivate ComAddin. I have set to see the Excel Instance with Show object, and after checking the COM list, its working. i can disable or enable COM but AddIn is not active among the ribbon panel. Is something missing? in VBA this kind of approach works. I have added office.dll so i can use Microsoft.Office.Core namespace.   code below: Dim wb as Object = GetWorkbook(handle,workbookname) Dim app as Object = wb.Application Dim addin As COMAddIn Try     For Each addin In app.COMAddIns         If addin.Description = AddInDescr Then    If ActivateCom = True     If addin.Connect = False Then addin.Connect = True    Else     If addin.Connect = True Then addin.Connect = False    End If   End If     Next Success = True Catch e As Exception  Success = False  Message = e.Message Finally  wb = Nothing  app = Nothing End Try Tue, 22 May 2018 18:50:00 GMT PavelKrál 2018-05-22T18:50:00Z https://community.blueprism.com/t5/Product-Forum/SAP-Analysis-for-Excel/m-p/62719#M15774 Hi, If i open excel manually, Analyissi tool is active, If i create instance or open Workbook from BP, analysisi is not active... in the com addins its telling me its load at startup and active, but its not.
