WHEN I RUN THE FOLLOWING CODE IN FORM INIT METHOD

THIS.oCrystalReports = CREATEOBJECT('CrystalRuntime.Application')
THIS.oReport = CREATEOBJECT('CrystalRuntime.Report')
THIS.oReport = THIS.oCrystalReports.OpenReport('reports\balCodeWidth.rpt')
THIS.addObject('oleCRViewer','oleControl','crViewer.crViewer')
THIS.oleCRViewer.Top = 1
THIS.oleCRViewer.Left = 1
THIS.oleCRViewer.Height = THISFORM.Height - 2
THIS.oleCRViewer.Width = THISFORM.Width - 2
THIS.oleCRViewer.ReportSource = THISFORM.oReport
THIS.oleCRViewer.ViewReport()


System prompt me following error :

OLE exception error: Exception code c0000005. OLE object may be corrup

Why?
