Crystal reports refuse running on pc

Hello there i have project which runs very well on my Windows 7 pc 32bit. but the issue comes when running reports. it brings the following error

"The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception.\n\n   at CrystalDecisions.CrystalReports.Engine.ReportDocument..ctor()

   at Octopus.Reports.Report.LoadDocument()

   at Octopus.Reports.Report.GetDocument()

   at Octopus.Reports.ReportService.LoadReport(Report report)

   at Octopus.Reports.Forms.ReportBrowserControl.OnLoadReport(Object sender, DoWorkEventArgs e)

   at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)

   at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)"

I have installed CRRuntime_32bit_13_0_11 and Crystal Reports Viewer 2008 but all in vain. could it be a windows issue?

I need your help. Please any one

Thank you
