I am facing a problem in my application.
I have some section in application from where user can download data in excel file.Code is working absolutely fine in local, Means file is getting download properly in local with every browser. But when we download file from test or live server its shows a popup with following error

“C:\Users\PHT~1.AMI\AppData\Local\Temp\hXybMbIw.xlsx.part
could not be saved, because the source
file could not be read. Try again
later, or contact the server
administrator.”

in case of firefox browser only.

I am using following code for file download

   function ExportToExcel(isJdl) {
        var url = '/Product/ExportToExcel?isJdl=' + isJdl
                + "&projID=" + _projID
                + "&PlanPages=" + escape($("#PlanPages").val())
                + "&SpecSections=" + escape($("#SpecSections").val())
                + "&Addenda=" + escape($("#Addenda").val())
                + "&HighLite=" + $("#chkHighLite").attr("checked");
        Download(url);
    }

    function Download(url) {
        var win = window.open(url, "DownloadWin", "resizable=0,status=0,toolbar=0,width=600px,height=300px");
        win.focus();
        win.moveTo(100, 100);
    }

Controller Code is as follow:-

public void ExportToExcel(bool isJdl, string projID, string planPages, string specSections, string addenda, string HighLite)
        {
            int pID = int.Parse(projID.Decrypt());
            bool HightLiteVal = false;
            if (!string.IsNullOrEmpty(HighLite))
                HightLiteVal = Convert.ToBoolean(HighLite);

            Highmark.BLL.Models.Project proj = Highmark.BLL.Services.ProjectService.GetByID(pID);


            if (proj != null)
            {
                proj.PlanPages = planPages;
                proj.SpecSections = specSections;
                proj.Addenda = addenda;
                proj.HighLite = HightLiteVal;
                using (OfficeOpenXml.ExcelPackage pck = new OfficeOpenXml.ExcelPackage())
                {

                    OfficeOpenXml.ExcelPackage pck1 = Highmark.BLL.Services.ProjectService.GetExcelFile(isJdl, pck, pID, proj, planPages, specSections, addenda);

                    string name = string.Format("{0}", proj.ProjectName);
                    if (pck1.Workbook.Worksheets.Count > 0)
                    {
                        //Write it back to the client
                        Response.ContentType = "Application/vnd.ms-Excel";

                        //Remove Invalid Character from File Name
                        name = name.RemoveInvalidCharFromFileName();

                        Response.AddHeader("content-disposition", "attachment;   filename=\"" + name + "_HighEST.xlsx\"");
                        Response.BinaryWrite(pck1.GetAsByteArray());
                    }
                }

            }
            else
                Response.Write("Error: Invalid request, please try again");
        }

Any help is appreciated.
Thanks

    Do you have some FF download manager extension?

    Anyway, this problem usually happens when your security software stops the download and then resumes it.

    if the file is being downloaded to you temp folder, FF might have problems accessing this folder and resume the download.

    Another solution might be to close FF and delete this file: “compreg.dat” from the profile folder.
