MS Access 2007 Macro no longer works

I had a problem some time ago with a macro, which I reported here:

https://www.experts-exchange.com/questions/28261009/MS-Access-Macro-no-longer-works.html

The solution worked for a while, but my system stopped working and I had to reinstall Windows 8.1 and all applications, and now the macro does not work.

As before, I have confirmed that the reference to the Microsoft Excel 15.0 Object Library is checked.

Option Compare Database

Function ExportToIMM()
    Dim filepath As String, xlapp As Object, xldoc As Object
     
    filepath = "C:\Users\Lev\Desktop\ATR.xls"
    filepath2 = "C:\Users\Lev\Desktop\ATR.txt"
    DoCmd.OutputTo acOutputTable, "RecentlySentAnswers", acFormatXLS, filepath
     
    Set xlapp = CreateObject("Excel.Application")
    Set xldoc = xlapp.Workbooks.Open(filepath)
    xlapp.DisplayAlerts = True
    xldoc.SaveAs filepath2, xlCSV
     
    xldoc.Close False
    xlapp.Quit
    deedCSV = 1
End Function

Select allOpen in new window

The error is
Run-time error '429':
ActiveX component can't create object

I do not know what to do now to get this to work.

At the same time, when I open the project (ADP file) I am told that it is in read-only mode, even though the folder e:\my documents has been listed as a "trusted zone". I saved the file with a different name (same folder), and am now working with that, but perhaps this is related.

Thank you.
