[RESOLVED] Imports CrystalDecisions question

I just started working .Net 2005. It comes with a version of Crystal Reports.
I created a report and tested the exe on another machine to see if there would be a portablity issue, but it worked fine.
Then I added these statements,

Code:

---

Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared

---

so I could use this code,

Code:

---

Dim cr As New ReportDocument
cr.Load("c:\standby\standby\CrystalReport3.rpt", OpenReportMethod.OpenReportByDefault)
cr.Database.Tables(0).Location = Application.StartupPath & "\water_net.mdb"
CrystalReportViewer1.ReportSource = cr

---

Now I get an exception when I install and run the App on another machine.
Do I need to install or register "CrystalDecisions"?

any information would be appreciated, Thanks

Adding the Crystal Reports Merge Modules solved the problem.
