I've used Ron Bruin's email routine in a workbook that creates a PDF of a particular sheet and then brings up Outlook to allow the entering of an email address and to send. I've got this running on several computers running the same version of Office. On a select few of these computers, I get this error from the code.

Else
        MsgBox "Not possible to create the PDF, possible reasons:" & vbNewLine & _
               "Microsoft Add-in is not installed" & vbNewLine & _
               "You Canceled the GetSaveAsFilename dialog" & vbNewLine & _
               "The path to Save the file in arg 2 is not correct" & vbNewLine & _
               "You didn't want to overwrite the existing PDF if it exist"
    End If
Is there something missing on these computers that would cause this problem? I've checked the references in the workbook and Microsoft Outlook 15.0 Object Library is checked. I'm a novice and just need a little advise. Any ideas?
