How to stop running "ThisWorkbook" codes when opening Excel file by macro

Hi everybody,

I'd like to ask you for help in this particular case:

- I have got an Excel file, that runs a macro that opens another workbook and copies over the data from this workbook

- the problem is that the other workbook runs a macro (launch userform) whenever it's opened, which is annoying for the user.

Do you have any idea, if one can actually somehow turn off "ThisWorkbook" codes?

    Private Sub Workbook_Open()
    Dim Language_Windows As Integer
    Dim Language As Integer
    Dim FCFF_Value
       
        
    'Hodnota Free Cash Flow to the Firm (FCFF)
        FCFF_Value = ActiveWorkbook.Worksheets("3_FCF").Range("I64")
    
    'Show 
        If Application.Max(FCFF_Value) = 0 And Application.Min(FCFF_Value) = 0 Then
        
            'Detect the language of the system
            Language_Windows = Application.International(xlCountrySetting)
    
            'Choose the language version according to the system language
            If Language_Windows = 420 Then
                Language = 1
            Else
                Language = 2
            End If
                   
            'Language version that has been chosen by the user already before
            Worksheets("1_Info").Range("Language") = Language
        Else
        
            'Do nothing
        End If
        
    'Opens the first/intial sheet
    ActiveWorkbook.Sheets("1_Info").Select
    
    'The choice of the language version of the userform
        If Worksheets("1_Info").Range("Language") = 1 Then
        
        'Shows Czech version
            UserForm_CZ.Show
        Else
        
        'Shows English version
            UserForm_EN.Show

        End If
End Sub

Thank you for any suggestion!

Thank you! Works great!
