Cannot send email using Outlook component!

Hi,
I'm working on a VB program which uses a DHTML page to collect a user survey. When the user clicks "Submit" on the survey page, I have code to collect the survey data, create a results file, then email it to a specific recipient.

I'm deploying the application using the VB6 Packaging and Deployment Wizard, and it is linked with the Outlook 9.0 project reference.

This works great, if Outlook is installed on the user's machine. However, if Outlook is not installed, I cannot send the emails, even though the VB-created installer drops a reference to the Outlook object library on the user's PC.

Is this by design, or am I doing something wrong here? The code is posted below.

Thanks in advance
Eric

Dim emailAddr As String, myDate As String, subjLine As String

' format subject line
Dim name As String
name = tbName.Value
' grab the name from the web page.
res = SplitName(name)

myDate = Date
subjLine = "Pilot survey results- " & fName & " " & lName & " - " & myDate
emailAddr = "name@location.com"
Dim olApp As Outlook.Application
Set olApp = CreateObject("Outlook.Application")

Set msg = olApp.CreateItem(olMailItem)
Set myRecipient = msg.Recipients.Add(emailAddr)
Set myAttachments = msg.Attachments
myAttachments.Add "c:\survey\data.results", olByValue, 1, "Survey Results"
msg.Subject = subjLine
msg.body = subjLine

'send message
msg.Send

Does the user have any MAPI compliant program installed? I believe that this may be the issue.
