Class not registered - CrystalPrintControl

Question

I cannot resolve this error when running my ASP.NET application under IIS. It works fine on my development machine with the full CR for VS2010 install.
The code lines concerned are:
ISCDReportClientDocument foo = _rptDoc.ReportClientDocument;
PrintOutputController bar = foo.PrintOutputController;
PrintReportOptions fooReportOptions = new PrintReportOptions();
fooReportOptions.PrinterName = Properties.Settings.Default.DefaultPrinter;
fooReportOptions.JobTitle = "RptJobTitle";
bar.PrintReport(fooReportOptions);
( printtoprinter still works, but I need the job title ability )
Server particulars:
2003 Server R2 Standard Edition SP2
IIS v6.0
.NET 4 installed
Crystal Reports Version:  CR 32-bit Redistributable 13.0.1
The PrintControl.cab is located in my aspnet_client/system_web/4_0_30319/crystalreportviewers13/ActiveXControls virtual directory.
I've tried adding the following to my web.config (as suggested by crnet_dg_2010_en.chm developer's guide):
    <sectionGroup name="businessObjects">
      <sectionGroup name="crystalReports">
        <section name="crystalReportViewer" type="System.Configuration.NameValueSectionHandler" />
        <section name="printControl" type="System.Configuration.NameValueSectionHandler" />
      </sectionGroup>
    </sectionGroup>
  <businessObjects>
    <crystalReports>
      <crystalReportViewer>
        <add key="resourceURI" value="~/crystalreportviewers13" />
      </crystalReportViewer>
      <printControl>
        <add key="url" value="http://localhost/PrintControl.cab" />
      </printControl>
    </crystalReports>
  </businessObjects>
Please help.  Has anyone been able to deploy to IIS 6 and use the PrintController?

I've tried redistributables:
CRforVS_redist_install_32bit_13_0.zip
CRforVS_redist_install_32bit_13_0_1.zip
I located C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers13\ActiveXControls on my development PC and it seems to match the IIS server's aspnet_client...../ActiveXControls files.
I confirmed that IIS knew where to find the CR files by installing a "spike" project which uses the Crystal Reports Viewer.  This worked fine, and the page source showed the correct path to the crystalreportviewer13 directory.
What seems to be broken is the PrintControl portion under crystalreportviewers13\ActiveXControls.  If the redist installer didn't register this part with the OS, how could I know?  Does it also have to register it with IIS?
Does anyone have experience getting something like the following working on an ASP.NET 4 page in IIS 6 (or even 7)?
protected void Button1_Click(object sender, EventArgs e)
            ReportDocument _rptDoc = new ReportDocument();
            _rptDoc.Load(Server.MapPath("./CrystalReport1.rpt"));
            _rptDoc.PrintOptions.PrinterName = "<PrinterNameHere>";
            ISCDReportClientDocument foo = _rptDoc.ReportClientDocument;
            PrintOutputController bar = foo.PrintOutputController;
            PrintReportOptions fooReportOptions = new PrintReportOptions();
            fooReportOptions.PrinterName = _rptDoc.PrintOptions.PrinterName;
            fooReportOptions.JobTitle = "ReportFoo";
            bar.PrintReport(fooReportOptions);
