    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>

    <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)

    hi manish,

    have you made sure you are using the correct crystal report version on your code?

    besides, you also need to make sure that the application pool is set to operate under LOCAL SERVICE permission. Additionally, please make sure you copy the crystalreportviewer folder to your working folder.

    Please mark this response as "answer" it helps you. Thanks heaps!
