Specify Which Paper Tray Will Be Used For A Report?

I need to specify which paper tray will be used for a report but I keep hitting dead ends.

I started out using code like this:

ReportDocument.PrintOptions.PaperSource = CrystalDecisions.[Shared].PaperSource.Lower

I tryed every option in the enumeration and it always pulled from the upper tray. I searched the web and found a number of people said "PaperSource" doesn't work, use "CustomPaperSource" instead. I tried it, but discoved CustomPaperSource doesn't appear to be a method of PrintOptions because the command is not recognized and won't compile. Sample:

For Each printerSource In printerSettings.PaperSources
If printerSource.SourceName.ToString = "Tray 1" Then
reportPaperSource = printerSource
End If
Next
ReportDocument.PrintOptions.CustomPaperSource = reportPaperSource

I found a Hot fix on the Business Objects site and applied it successfully.

I also fould they recommend Crystal Report Service Pack 3. When I run it, it gives me a message: "Failed to read/update the registry for the Crystal Reports 10.0 Service Pack 3 -199".

I have 2 questions:

A) Is there a way to get my original PaperSource to work? It seems silly to have commands that don't do anything, so there must be a way to get it to do something.

B) Is there a way to get this or some other service pack to load so I can use the new command (CustomPaperSource)?
