Request could not be submitted for background processing

Question

Using Crystal Reports XI R2
<br />Using Visual Studio .NET 2005
<br />
<br />Here's the scenario.  The client goes to run a report and specifies the filters they want for the report.  We load a pre-built rpt with no saved data and pass the filters in to the report via the parameters.  We then generate and export the report to another rpt file with saved data using the PULL method from the report itself.  When the viewer wants to view the report the file (with saved data) is copied locally to the web server and the CrystalReportViewer control is pointed at the rpt with the saved data in it.  In almost every case the reports come up fine and display in the viewer no problem.  The error above (Request could not be submitted for background processing) tends to show itself in the CrystalReportViewer control whenever the report has large amounts of data (like 8 megs worth).  I've tried everything I can find on this issue including the steps listed in the white paper for this issue.
<br />
<br />So just to be clear on the steps taken:
<br />1)If I take the saved rpt and open it in Crystal Reports itself then it works fine.
<br />2)If I point to the rpt with the CrystalReportViewer control in my development environment it works fine.
<br />3)I've run Process Monitor and there were a couple of access denied messages to one of the HKLM registry keys but I modified the permissions so those went away but the problem still remained
<br />4)As far as I can tell the report has no design issues.  Nothing runs over any edges, no overlapping of any kind, the Font itself exists on the machine in question.
<br />5)Its not a dataset problem since the report is using the PULL method to generate itself plus the rpt with saved data is correctly generated its just showing the above error when trying to view it in the control.
<br />6)The client is using a WIndows 2003 server, with 4 Quad Core processors and 8 gigs of RAM and 100 gigs of hard drive space remaining (so hardware is not an issue)
<br />7)In code the ReportDocument object is inside a using statement (C# .NET) and only exist for the brief period needed to create the rpt with saved data.  So they are getting closed and disposed of correctly.  Also as pointed out above the rpt with saved data is already being generated correctly its just not displaying in the control.
<br />
<br />So to recap on a web server used by multiple people whenever a user tries to view a saved rpt file that has a large amount of data using the CrystalReportViewer control the error above tends to get generated even though the vast majority of the reports do display.  I'm at a loss for what else to try to make the report display correctly in the control.  Any thoughts would be helpful.

Make sure you are using SP6:

Runtime

msi:

Other than that, I'd consider installing the CR designer - as a test, on the user machine and see if the designer can open the report.
