How to remove Load Report Failed Error in Crystal Reports version 13.0?

I am developing a simple Windows form app using Crystal Report (Version 13.0) and .NET Framework 4.0 as well as VS 2013. What i am doing is that i have a Crystal report viewer on the form which is supposed to show/load my report when button is clicked. My code to load a report is:

ReportDocument rpt = new ReportDocument(); rpt.Load(@"e:\<path>\CrystalReport1.rpt"); crystalReportViewer1.ReportSource = rpt; crystalReportViewer1.Refresh();

Problem i am getting is that whenever i click button, an exception occurs saying this:

CrystalDecisions.Shared.CrystalReportsException was unhandled HResult=-2146232832 Message=Load report failed.

Solutions i have tried are:

1. Checked the path again and again.
2. Checking file permissions on the temp folder as well as on the folder where my report resides.

But all in vein. Can somebody please tell me as what's going behind the scene?
