Error in Loading DLL while using late binding (Outlook)

[CBass78]

tl;dr - Converted from early to late binding to email a report using Outlook, now getting "Error in Loading DLL"


Good morning! I developed a tool for our production operations that automatically generates an email when a report is run. It was working fine for me using early binding, but then I was asked to roll it out to multiple users so I converted to late binding. It still works fine for me, but the other users are getting "Error in Loading DLL" faults when running the report. I thought the entire point of late binding was avoiding compatability issues across different versions of Excel?
Anyway, here's my code:

' Save and capture some variables
    ThisWorkbook.Save
      Dim DateCode
        DateCode = Range("E4")
      Dim EmailDate
        EmailDate = Range("B4")
      Dim FileNaem
        FileNaem = Range("B3")
' Open Email to send results
Dim OutApp As Object, objOutlookMsg As Object, objOutlookRecip As Object, Recipients As Object
  Set OutApp = CreateObject("Outlook.Application")
  Set objOutlookMsg = OutApp.CreateItem(0)
  Set Recipients = objOutlookMsg.Recipients
  Set objOutlookRecip = Recipients.Add("[EMAIL="people@places.com"]people@places.com[/EMAIL]")
  objOutlookRecip.Type = 1

  objOutlookMsg.Subject = EmailDate & " " & FileNaem
  objOutlookMsg.Attachments.Add ActiveWorkbook.FullName  
  For Each objOutlookRecip In objOutlookMsg.Recipients
    objOutlookRecip.Resolve
  Next
  
    Application.ScreenUpdating = True
  
  objOutlookMsg.Display

  Set OutApp = Nothing

Anything obviously wrong?
