Add-ins not loading when opening excel file progra

问题:

I've seen some similar problems described by others before but no real solution. And I'm sure there is one.

I have a .XLA-add in configured to be loaded when I open up Excel. It works fine when I open documents or Excel it self. However, when my BI-system programmatically creates and opens an Excel-file the add-in does not get loaded. The BI-system opens Excel in a new instance so it does not help to have opened Excel on beforehand (and thereby the .XLA-add in)

If i Check Options-Add Ins it looks like the add-in is loaded but it is not!

What I've tried (and that does work) is to insert this function into the created excel-file and "reload" the add-ins, but I want to find an automated solution!

Function ReloadXLAddins(TheXLApp As Excel.Application) As Boolean

Dim CurrAddin As Excel.AddIn

For Each CurrAddin In TheXLApp.AddIns
    If CurrAddin.Installed Then
        CurrAddin.Installed = False
        CurrAddin.Installed = True
    End If
Next CurrAddin

End Function

Is there any way to load my Add ins automatically when instancing excel programmatically?

Any tips, solutions or workarounds are highly appreciated!

Best regards.

This may not be possible in VBA. I have come across this problem before, and used the implementation found here: Excel interop loading XLLs and DLLs

However, that solution is for C#. The steps required may not be possible when coming from inside of an Excel VBA script. Perhaps there are some VBA implementations you can look at, but wanted to give you some sort of starting place because I know that is a frustrating place to be.
