Run same macro in different versions of Excel / Outlook / Word

Question

I generate reports to send to different branches. I run a macro that creates protected reports (*.xlsm). These reports have a space for comments for the Branch Managers, with a "send Comments" button that run this macro below.

I suggested the following references to add if the macro does not work.

The Branch Managers have different versions of MS Office (Excel, Outlook, etc.) on their laptops. When they try to Run, it shows errors, such as: "Error in Loadind DLL"; Error2, etc.

What should be done on the Branch Managers side to run this Macro?

Sub CommentsEmail()

Dim template As Workbook
Dim dashboard As Worksheet
Dim comments As Worksheet
Dim OutApp As Object
Dim OutMail As Object
Dim olApp As Outlook.Application
Dim mymail As Outlook.mailItem
Dim objSel As Word.Selection
Dim commentsrange As Range
Dim branch As String
Dim Sendto As String

UpdateScreen = False

Shell ("Outlook")

Set olApp = New Outlook.Application
Set mymail = olApp.CreateItem(olMailItem)
Set template = ActiveWorkbook
Set dashboard = template.Worksheets("Dashboard")
Set comments = template.Worksheets("Comments")
branch = dashboard.Cells(1, 25)
Sendto = comments.Cells(2, 10)
Set commentsrange = comments.Range(Cells(7, 1), Cells(52, 4))

template.Activate


Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)

'OutMail.Display
Dim wordDoc As Word.Document
Set wordDoc = OutMail.GetInspector.WordEditor

Set objSel = wordDoc.Windows(1).Selection

        'construct the body of the email here
        With objSel

            'first text
            .InsertAfter "Dear All," & vbCrLf
            .Move wdParagraph, 1

            'second text
            .InsertAfter vbCrLf & "See below the Comments for Flash Indicator - " & branch & vbCrLf & vbCrLf
            .Move wdParagraph, 1

            'copy a range and paste a picture
            commentsrange.Copy ''again, you need to modify your target range
            .PasteAndFormat wdChartPicture
            .Move wdParagraph, 1

            .InsertAfter vbCrLf & "Let us know of any questions." & vbCrLf & vbCrLf
            .Move wdParagraph, 1

            .InsertAfter vbCrLf & "Kind Regards," & vbCrLf
        End With

        OutMail.To = OutMail.To & ";" & Sendto

        With OutMail

         .Subject = "Comments on Flash Indicator Results - " & branch
         .Attachments.Add (ActiveWorkbook.FullName)
         .Display
        End With

On Error GoTo 0

        Set OutMail = Nothing
        Set OutApp = Nothing


        With Application
            .ScreenUpdating = True
            .EnableEvents = True
        End With
        Exit Sub

End Sub

Is this still early binding? If yes, I am totally lost.
