This download will install a series of components to help in existing Microsoft Office files (such as Microsoft Office Access 2010 (*.mdb and *.accdb) files and Microsoft Office Excel 2010 (*.xls, *.xlsx and *.xlsb) Files) and other data sources (such as Microsoft SQL Server) to transfer data .
It also supports establishing a connection with existing text files .
In addition, ODBC and OLEDB drivers will be installed for application developers to use when developing applications that connect to the Office file format .

The Access 2010 database engine redistributable package is not used for the following purposes:

As a general replacement for Jet (if you need a general replacement for Jet, you should use SQL Server Express Edition ).
As an alternative to Jet OLEDB provider for server-side applications.
As a general word processing, spreadsheet or database management system-used to create documents. (You can use Microsoft Office or Office Automation to create files supported by Microsoft Office.)
Used by a server-side program running under a system account by a system service or code, or will handle multiple user identities at the same time, or can be highly reentrant and expect stateless behavior. For example, a program that runs from the task scheduler when no user is logged in; or, a program that is called from a server-side Web application like ASP.NET; or, a distributed component that runs under COM+ services.

Installation requirements

Supported operating system

Windows 10, Windows 7, Windows 8, Windows Server 2003, Windows Server 2003 Service Pack 1, Windows Server 2003 Service Pack 2, Windows Server 2008 R2, Windows Server 2008 Service Pack 2, Windows Server 2012 R2, Windows Vista Service Pack 1, Windows XP Service Pack 2

Only 32 Access database engine can be used on Windows XP Service Pack 3 ; if you previously installed Office, the Office is 32, then should correspond to install the 32-bit ACE; Office is 64, it should correspond installation 64 Bit of ACE.
AccessDatabaseEngine.exe 、AccessDatabaseEngine_X64.exe

Microsoft Access 2010 database engine installation instructions

Note: Before installing this download, you must first uninstall any previous version of the Access database engine from your computer by using "Add/Remove Programs" in the "Control Panel".

To install this download:

Download the file by clicking the "Download" button and saving the file to the hard drive.
Double-click the "AccessDatabaseEngine.exe" program file on the hard disk to start the installation program.
Follow the instructions on the screen to complete the installation.

To use this download, please do the following: (Otherwise, you will not be able to connect successfully:)

If you are an application user, please consult your application documentation for details on how to use the corresponding driver.
If you are an application developer using OLEDB , please set the Provider parameter of the ConnectionString property to "Microsoft.ACE.OLEDB.12.0".
For example: Provider=MICROSOFT.ACE.OLEDB.12.0;
if you want to connect to Microsoft Office Excel data, please add the corresponding OLEDB connection string extended attributes according to the Excel file type:

file type (extension) extended attributes
------ -------------------------------------------------- -------------------------------------
Excel 97-2003 Workbook (.xls) "Excel 8.0 "For example: Extended Properties=Excel 8.0;
Excel 2007-2010 workbook (.xlsx) "Excel 12.0 Xml" For example: Extended Properties=Excel 12.0 Xml;
Macro-enabled Excel 2007-2010 workbook (.xlsm) "Excel 12.0 macro "
Excel 2007-2010 Non-XML Binary Workbook (.xlsb) "Excel 12.0"
```
Provider=MICROSOFT.ACE.OLEDB.12.0;Data Source=D:\开发包\饲料分批次进销存-存货计价和条码\A1.xls;Extended Properties=Excel 8.0;Persist Security Info=False
Provider=MICROSOFT.ACE.OLEDB.12.0;Data Source=D:\开发包\饲料分批次进销存-存货计价和条码\A1.xlsx;Extended Properties=Excel 12.0 Xml;Persist Security Info=False
```
This is important!
If you are an application developer who uses ODBC to connect to Microsoft Office Access data, please set the connection string to "Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=path to mdb/accdb file "
If you are an application developer who uses ODBC to connect to Microsoft Office Excel data, please set the connection string to "Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)}; DBQ=path to xls/xlsx/xlsm/xlsb file"

To delete this download, please do the following:
To delete the download file itself, delete the file AccessDatabaseEngine.exe

On the Start menu, point to Settings, and then click Control Panel .
Double-click "Add/Remove Programs" .
In the list of currently installed applications, select "Microsoft Access 2010 Database Engine" , and then click "Remove" or "Add/Remove" . If a dialog box appears, follow the instructions to remove the program.
Click "Yes" or "OK" to confirm that you want to delete the program.

other instructions:

Office System drivers are only supported in certain specific situations, including:

Desktop applications that read or write various file formats (including Microsoft Office Access, Microsoft Office Excel, and text files).
Transfer data between supported file formats and databases (such as SQL Server). For example, use the SQL Server Import and Export Wizard or SQL Server Integration Services to import data from an Excel workbook to SQL Server (provided that the SSIS job runs in the context of a logged in user with a valid HKEY_CURRENT_USER registry hive).

2. Why use ACE engine?

2.1, Microsoft.Jet.OLEDB.4.0 engine Microsoft has not been maintaining it for a long time, and can only handle data sharing between MS Office 2003 and below and MS Sql Server

Jet.OLEDB.4.0 can only handle data sharing between MS Office 2003 and below and MS Sql Server; and Microsoft has long no longer maintained it. It is a product of ADO.

2.2. The Microsoft.ACE.OLEDB.12.0 engine is a product of ADO.Net. It is currently the only two mainstream large-scale relational database engine technologies on the market that Oracle’s ODP goes hand in hand with it.

ACE.OLEDB.12.0 can handle data sharing between MS Office 97 and the latest MS Office 2019 versions and MS Sql Server. Microsoft will always maintain it, and it plays an important role in the underlying data processing of the .Net strategy and the current Microsoft cloud universe database Cosmos DB and Azure operating system database. It is a product of ADO.Net.

2.3. ADO.Net and ADO are database engine technologies with completely different architectures.

3. Why does Delphi use ACE engine or Jet engine instead of OleObject or OleVariant technology based on ComObj technology?

The ACE engine or Jet engine is N orders of magnitude faster than ComObj.pas' CreateOleObject.
Because it is the native method of Microsoft's OLE database engine: it only takes about 20 seconds to export 1 million records to Excel.

Fourth, use ACE engine technology in Delphi control

4.1. Technical environment to be deployed
