    With regard to this previous thread:

    2 things.

    First, I've examined the code and I'm a bit confused.  I thought this technique only worked for XLS format, not the new XLSX.

    Second, I have had an app up and running for some time now using that technique to import xls files without any problem. 

    Now, suddenly I cannot perform this operation locally in Visual Studio.2012  (It was working fine during the original development)  It crashes: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

     As far I know this is part of the package Microsoft Access Database Engine 2010.  I have version 14 installed.

    My apologies.  Let's forget this.

    It seems definite that my problems all stem from the installation of 64-bit Office 2013 on my current development machine.

    I'm trying to Export Telerik Grid to Excel by using code(SharePoint 2013):

    using Telerik.Windows.Documents.Spreadsheet;
    using Telerik.Windows.Documents.Spreadsheet.FormatProviders;
    using Telerik.WinControls.Export;
    using Telerik.Windows.Documents.Core;
    using Telerik.Windows.Zip;
    using Telerik.Web.UI.Export;
    using Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml;
    using Telerik.Windows.Documents.Spreadsheet.Model;
    using Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx;
    using Telerik.Windows.Documents.Fixed;

            protected void btnEportToXLS_Click(object sender, EventArgs e)

                if (TicketsGrid.Items.Count > 0)

                        TicketsGrid.ExportSettings.ExportOnlyData = true;
                        TicketsGrid.ExportSettings.IgnorePaging = true;
                        TicketsGrid.ExportSettings.OpenInNewWindow = true;
                        TicketsGrid.MasterTableView.UseAllDataFields = true;
                        TicketsGrid.ExportSettings.FileName = "C:\\ExcelFile.xlsx";// Guid.NewGuid().ToString();
                    catch (Exception exc)



            private GridItemType[] supportedItemTypes = new GridItemType[] 


    After executing the code getting exception:
    Could not load file or assembly 'Telerik.Windows.Documents.Spreadsheet, Version=2016.1.106.45, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified.

    Any suggestions please?
