Crystal Reports - "Failed to load database information"

[Mark Lemoine]

Good Morning, apologies if this isn't the proper group for this
question -

We've got a vb.net 2003 web app that's been running fine for several
years now. Just recently, we have tried to install on a Windows
Server 2003 Standard 64bit server and are receiving the following
exception when we try to run our reports:

CrystalDecisions.CrystalReports.Engine.DataSourceException: Error in
File C:\[...]\Reports\Waiver.rpt:
Failed to load database information.

This is our first attempt on Windows 64bit, but we don't really know
if the issue is with this version of the OS (we can run fine on
Windows 2003 32bit).

Framework 1.1sp1 and Framework 2.0 are installed on the server. We
installed the Crystal Reports 9 .Net Server runtime successfully (I
can see the expected assemblies in the gac and in the common files
locations).

We are using the ReportDocument object and are passing it a dataset
with the SetDataSource method (ie, the crystal engine doesn't have a
live connection to the db).

Here is the stack trace on the exception, if that's helpful:

.N(String -, EngineExceptionErrorID 0) +541
.I(Int16 !, Int32 ") +623

CrystalDecisions.CrystalReports.Engine.FormatEngine.GetPage(PageRequestContext
reqContext) +562

CrystalDecisions.ReportSource.LocalReportSourceBase.GetPage(PageRequestContext
pageReqContext) +159
CrystalDecisions.Web.ReportAgent.|(Boolean Z) +208
CrystalDecisions.Web.CrystalReportViewer.OnPreRender(EventArgs e)

System.Web.UI.Control.PreRenderRecursiveInternal() +77

System.Web.UI.Control.PreRenderRecursiveInternal() +161
System.Web.UI.Page.ProcessRequestMain(Boolean
includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Thanks in advance for any advice!
