The Microsoft.Jet.OLEDB.4.0 provider is not registered on the local machine Background Amphis Customer is designed to work on 32 or 64 bit PCs running Windows XP, Windows Vista, Windows 7 or Windows 8 Pro, but on Windows XP 64 bit (and possibly other operating systems) it is possible that some of the Microsoft OLEDB DLLs have not been registered. In your application, update the connection string from “ Provider=Microsoft.Jet.OLEDB.4.0; ” to “ Provider=Microsoft.ACE.OLEDB.12.0; ”. It is possible to open Excel, Access and text files on 64-bit systems. You can either configure your app to go 32-bit or you can change your application to use the new 64-bit drivers. Here Mudassar Ahmed Khan has explained how to download the Microsoft.ACE.OLEDB.12.0 provider for 32bit and 64bit. In order to download the Microsoft.ACE.OLEDB.12.0 provider for 32bit and 64bit, you will need to download the Microsoft Access Database Engine 2010 Redistributable file. TAGs: ASP.Net, Excel, Tips, OLEDB. Provider=Microsoft.Jet.OLEDB.4.0 If you want to work with Excel 2007 or newer file formats then you need to use ACE OLEDB provider instead of Jet. Jet does not recognize new formats. In C# without using Excel Object we can insert, edit, delete, select etc. In cell content of an Excel file using OLEDB. You have to import System.Data in the project for doing these operations. For add new content in the cell or insert a new content, We can use the INSERT command like in SQL Operations. Sample UPDATE sql.

Microsoft ACE OLEDB

With Office 2010, there are new drivers, the 2010 Office System Driver, which will be provided in both 32-bit and 64-bit versions. You can use these drivers to let your application connect to Access, Excel and text files in a 64 bit environment utilizing the new 64-bit drivers.

You don't need to buy or install the Office suite, the components are available as a separate download.

Microsoft Jet OLEDB

If you want to work with Excel 2007 or newer file formats then you need to use ACE OLEDB provider instead of Jet. Jet does not recognize new formats.

The Provider supports the following arguments:

Microsoft Jet Oledb 4.0 Driver

Data Source=

Path & Filename of the Excel workbook you want to process

Extended Properties='x'

'x' stands for one or multiple of the following extended properties separated by a semicolon:

• Excel 5.0: Excel 5 to 95 (xls-files)
• Excel 8.0: Excel 97 to 2003 (xls-files)
• Excel 12.0: Excel 2007 or later (xlsb-files, binary format) or 97-2003 Excel workbooks (xls-files)
• Excel 12.0 Xml: Excel 2007 or later (xlsx-files, macros disabled)
• Excel 12.0 Macro: Excel 2007 or later (xlsm-files, macros enabled)

HDR=

Specifying HDR=YES means that the test file contains a header row. A header row simply means that the first row in the text file is a list of fields, with all subsequent rows containing the actual data.

IMEX=

Value 1 tells the driver to always read 'intermixed' (numbers, dates, strings etc) data columns as text. Note that this option might affect excel sheet write access negative.

MaxScanRows=

Excel does not provide the detailed schema definition of the tables it finds. It needs to scan the rows before deciding the data types of the fields. MaxScanRows specifies the number of cells to be scanned before deciding the data type of the column. By default the value of this is 8. You can specify any value from 1 - 16 for 1 to 16 rows. You can also make the value to 0 so that it searches all existing rows before deciding the data type. You can change the default behaviour of this property by changing the value of [HKLMSoftwareMicrosoftJet4.0EnginesExcelTypeGuessRows] which is 8 by default.

ReadOnly=

You can open a Workbook in readonly mode by specifying ReadOnly=True. By Default Readonly attribute is False, so you can modify data within your Workbook.

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

Introduction

The Microsoft OLE DB Provider for Microsoft Jet and the Microsoft Access ODBC driver (Jet ODBC driver) provide an interface to Microsoft Office Access databases. The Microsoft OLE DB Provider for Jet and the Jet ODBC driver are available in 32-bit versions only.

Microsoft Jet Oledb Driver

For example, you have a 32-bit application that uses the Microsoft OLE DB Provider for Jet. If you migrate the application to run in the 64-bit mode, the application can't connect to the data source by using the Microsoft OLE DB Provider for Jet. This issue occurs because the application requires a 64-bit version of the Microsoft OLE DB Provider for Jet.

However, you can still use the 32-bit version of the Microsoft OLE DB Provider for Jet and the 32-bit version of the Jet ODBC driver. In a 64-bit Windows environment, you can run an application in the 32-bit mode. This enables the application to use the 32-bit version of the Microsoft OLE DB Provider for Jet or the 32-bit version of the Jet ODBC driver.

More information

The Jet Database Engine was designed to be a general-purpose database engine that's supplied together with Windows. The Access Database Engine, also called Access Connectivity Engine (ACE), is the Office database engine that's built from the foundation of Jet. ACE is provided in both 32-bit and 64-bit architectures. However, only one architecture is allowed on a device. The architecture of ACE must match the architecture of the Office installation on that computer. Both engines provide similar functionality, but ACE follows the design principles of Office and isn't suited for some of the previous scenarios that are supported by Jet. To make sure that ACE is the best solution for your scenario, read through all the intended use scenarios that are provided on the download page, Download Microsoft Access Database Engine 2016 Redistributable.

To determine whether ACE is already available on your computer, or which installation is recommended, see Unable to use the Access ODBC, OLEDB, or DAO interfaces outside Office Click-to-Run applications.
