compatibility vba 2016 VS vba 2019

Good evening to the whole forum and happy new year, I have a problem that I assume is related to the compatibility of the two versions of excel indicated in the title. I have a macro that with Excel 2016 works perfectly while I move it to another pc where I installed excel 2019the macro starts and immediately goes to the userform ignoring all the written code. Below I'll give you the code. In case it is necessary I can also attach the file... Thanks in advance to those who want to help me.


Ciao

Code:

---

Sub IMPORT_DATA()

Dim oExcel As Excel.Application
Dim strFile As String
Dim FileCorrente As Object
Dim r As Integer
Set FileCorrente = ActiveSheet
Set oExcel = New Excel.Application
'
mFolder = "E:\Bofetti\CHECK LIST\"


strFile = Dir(mFolder & "*.xlsx") ' assicurasi che l'estensione del file sia corretta
r = 12 'variabile riga
'inizia ciclo lettura
Do While strFile <> ""
    ' in oExcel ci vanno a finire di volta in volta _
      i file contenuti nella cartella
    oExcel.Workbooks.Open mFolder & strFile
   
   
    FileCorrente.Cells(r, 2) = oExcel.Worksheets("LGI Certificate Accessories").Cells(7, 4)  'D7
    FileCorrente.Cells(r, 3) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 1)  'A17
    FileCorrente.Cells(r, 4) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 6)  'F17
    FileCorrente.Cells(r, 5) = oExcel.Worksheets("LGI Certificate Accessories").Cells(31, 4)  'D31
    FileCorrente.Cells(r, 6) = oExcel.Worksheets("LGI Certificate Accessories").Cells(31, 13)  'M31
    FileCorrente.Cells(r, 7) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 16)  'P17
    FileCorrente.Cells(r, 8) = oExcel.Worksheets("LGI Certificate Accessories").Cells(18, 19)  'S18
    FileCorrente.Cells(r, 9) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 23)  'W17
    FileCorrente.Cells(r, 10) = oExcel.Worksheets("LGI Certificate Accessories").Cells(58, 9)  'I58
    oExcel.ActiveWorkbook.Close False
    strFile = Dir
    r = r + 1
   
   
   
   
 
Loop
' chiude e azzera variabili
oExcel.Quit
Set oExcel = Nothing






Range("A1").Select
End Sub

Your macro has no incompatibility with Excel 2019, I only cleaned it up a little.
If the path is correct and the files .xlsx are present give it another chance:

Code:

---

Option ExplicitSub IMPORT_DATA()
    Dim oExcel As Excel.Application
    Dim strFile As String
    Dim r      As Integer
    Dim mFolder As String
   
    Set oExcel = New Excel.Application
    mFolder = "E:\Bofetti\CHECK LIST\"      '<= check this path
    strFile = Dir(mFolder & "*.xlsx")            ' assicurasi che l'estensione del file sia corretta
    r = 12                                        'variabile riga
    'inizia ciclo lettura
    Do While strFile <> ""
        'in oExcel ci vanno a finire di volta in volta _
        'i file contenuti nella cartella
        oExcel.Workbooks.Open mFolder & strFile
        With ActiveSheet
            .Cells(r, 2) = oExcel.Worksheets("LGI Certificate Accessories").Cells(7, 4) 'D7
            .Cells(r, 3) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 1) 'A17
            .Cells(r, 4) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 6) 'F17
            .Cells(r, 5) = oExcel.Worksheets("LGI Certificate Accessories").Cells(31, 4) 'D31
            .Cells(r, 6) = oExcel.Worksheets("LGI Certificate Accessories").Cells(31, 13) 'M31
            .Cells(r, 7) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 16) 'P17
            .Cells(r, 8) = oExcel.Worksheets("LGI Certificate Accessories").Cells(18, 19) 'S18
            .Cells(r, 9) = oExcel.Worksheets("LGI Certificate Accessories").Cells(17, 23) 'W17
            .Cells(r, 10) = oExcel.Worksheets("LGI Certificate Accessories").Cells(58, 9) 'I58
        End With
        oExcel.ActiveWorkbook.Close False
        strFile = Dir
        r = r + 1
    Loop
    ' chiude e azzera variabili
    oExcel.Quit
    Set oExcel = Nothing
    Range("A1").Select
End Sub

I do remember there being a change in whether Excel opens multiple workbooks in the same instance of Excel or not, but I can't remember when this was.
Why are you starting a new instance of Excel anyway?
I've not tested the following but you can try the likes of:

Code:

---

Sub IMPORT_DATA2()
'Dim oExcel As Excel.Application
Dim strFile As String
Dim FileCorrente As Object
Dim r As Integer
Set FileCorrente = ActiveSheet
'Set oExcel = New Excel.Application
'
mFolder = "E:\Bofetti\CHECK LIST\"
strFile = Dir(mFolder & "*.xlsx")    ' assicurasi che l'estensione del file sia corretta
r = 12    'variabile riga
'inizia ciclo lettura
Do While strFile <> ""
  ' in oExcel ci vanno a finire di volta in volta _
  i file contenuti nella cartella
  Set wb = Workbooks.Open(mFolder & strFile)
   
  FileCorrente.Cells(r, 2) = wb.Worksheets("LGI Certificate Accessories").Cells(7, 4)    'D7
  FileCorrente.Cells(r, 3) = wb.Worksheets("LGI Certificate Accessories").Cells(17, 1)    'A17
  FileCorrente.Cells(r, 4) = wb.Worksheets("LGI Certificate Accessories").Cells(17, 6)    'F17
  FileCorrente.Cells(r, 5) = wb.Worksheets("LGI Certificate Accessories").Cells(31, 4)    'D31
  FileCorrente.Cells(r, 6) = wb.Worksheets("LGI Certificate Accessories").Cells(31, 13)    'M31
  FileCorrente.Cells(r, 7) = wb.Worksheets("LGI Certificate Accessories").Cells(17, 16)    'P17
  FileCorrente.Cells(r, 8) = wb.Worksheets("LGI Certificate Accessories").Cells(18, 19)    'S18
  FileCorrente.Cells(r, 9) = wb.Worksheets("LGI Certificate Accessories").Cells(17, 23)    'W17
  FileCorrente.Cells(r, 10) = wb.Worksheets("LGI Certificate Accessories").Cells(58, 9)    'I58
  wb.Close False
  strFile = Dir
  r = r + 1
Loop
' chiude e azzera variabili
'oExcel.Quit
'Set oExcel = Nothing
Range("A1").Select
End Sub

---

which can be cut down to (again not tested):

Code:

---

Sub IMPORT_DATA3()
Dim strFile As String, mFolder, wb
Dim FileCorrente
Dim r As Long
Set FileCorrente = ActiveSheet
'
mFolder = "E:\Bofetti\CHECK LIST\"
strFile = Dir(mFolder & "*.xlsx")    ' assicurasi che l'estensione del file sia corretta
r = 12    'variabile riga
Do While strFile <> ""
  Set wb = Workbooks.Open(mFolder & strFile)
  With wb.Worksheets("LGI Certificate Accessories")
    FileCorrente.Cells(r, 2).Resize(, 9).Value = Array(.Cells(7, 4), .Cells(17, 1), .Cells(17, 6), .Cells(31, 4), .Cells(31, 13), .Cells(17, 16), .Cells(18, 19), .Cells(17, 23), .Cells(58, 9))
  End With
  wb.Close False
  strFile = Dir
  r = r + 1
Loop
Range("A1").Select
End Sub

There were some version changes in the way Multiple Document Interface (MDI) and Single Document Interface (SDI). Don't know if that's the issue

This has been crossposted here: https://www.forumexcel.it/forum/thre...on-2019.44227/ where he seems to have hacked off the moderators since the thread's been closed and he's been 'repositioned' (banned from posting?) for a year for bad language.
Given that, I doubt we'll hear from him again, whether or not we've solved his problem…
