Crystal Reports: Fix for "Load report failed" error.

Error Message:

Crystal Report - Load Report Failed

This error occurs in the following scenarios.

Permission issue
The application must have access to the Temp folder. You have two choices to solve this (Choose any one).

1. How to Assign Permissions for the Windows Temporary Folder on the Web Servers[^]
   
2. ASP.NET Impersonation[^]

ASPNET machine account to be added to the Temp directory, so we have to specify username and password attributes for <identity> tag in Web.config file for identifying the IIS Authenticated Account or User.

<identity impersonate="true" userName="accountname" password="password" />

Invalid File path or File name

• Ensure the Report file name is correct (may be Typo or something. Example: Repotr1.rpt instead of Report1.rpt)
• Ensure the Report path is correct (Example: "Reports/Report1.rpt" instead of "~/Reports/Report1.rpt")
• Actually some of us forget to copy the report files to the publish folder (IIS virtual directory) so copy it.

Unmanaged resources
We must clean up the unmanaged resources(ReportDocument object) used in the page like below.

protected void Page_Unload(object sender, EventArgs e)
{
  if(RptDoc != null)
  {
    RptDoc.Close();
    RptDoc.Dispose();
  }
}

And another case is Crystal Reports Maximum Report Processing Jobs Limit[^].
