Installing OLE DB Driver for SQL Server
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
Azure Synapse Analytics
Analytics Platform System (PDW)
Note
Starting with version 19.3, installation of the Microsoft Visual C++ Redistributable is a prerequisite for installing the Microsoft OLE DB Driver 19 for SQL Server.
For the ARM64 driver installer, install the ARM64 Microsoft Visual C++ Redistributable package.
For the x86 driver installer, install the X86 Microsoft Visual C++ Redistributable package.
For the x64 driver installer, install both the X86 and X64 Microsoft Visual C++ Redistributable packages.
To install the OLE DB Driver for SQL Server, you need the msoledbsql.msi installer. Run the installer and make your preferred selections. The OLE DB Driver for SQL Server can be installed side-by-side with earlier versions of Microsoft OLE DB providers.
The files for OLE DB Driver for SQL Server (msoledbsql19.dll/msoledbsql.dll, msoledbsqlr19.dll/msoledbsqlr.rll) are installed in %SYSTEMROOT%\system32\ . Additionally, the x64 msoledbsql.msi installs 32-bit binaries in %SYSTEMROOT%\SysWOW64\.
Note
All appropriate registry settings for the OLE DB Driver for SQL Server are made as part of the installation process.
The header and library files for OLE DB Driver for SQL Server (msoledbsql.h and msoledbsql.lib/msoledbsql19.lib) are installed in %PROGRAMFILES%\Microsoft SQL Server\Client SDK\OLEDB\<major_version><minor_version>\SDK. Additionally, the x64 msoledbsql.msi installs the same files in %PROGRAMFILES(x86)%\Microsoft SQL Server\Client SDK\OLEDB\<major_version><minor_version>\SDK.
You can distribute OLE DB Driver for SQL Server through msoledbsql.msi. You might have to install OLE DB Driver for SQL Server when you deploy an application. One way to install multiple packages in what seems to the user to be a single installation is to use chainer and bootstrapper technology. For more information, see Authoring a Custom Bootstrapper Package for Visual Studio 2005 and Adding Custom Prerequisites.
The x64 msoledbsql.msi also installs the 32-bit version of OLE DB Driver for SQL Server. If your application targets a platform other than the one it was developed on, you can download versions of msoledbsql.msi for x64 and x86.
When you invoke msoledbsql.msi, only the client components are installed by default. The client components are files that support running an application that was developed using OLE DB Driver for SQL Server. To also install the SDK components, specify ADDLOCAL=All on the command line. For example:
msiexec /i msoledbsql.msi ADDLOCAL=ALL
Silent install
If you use the /passive, /qn, /qb, or /qr option with msiexec, you must also specify IACCEPTMSOLEDBSQLLICENSETERMS=YES, to explicitly indicate that you accept the terms of the end user license. This option must be specified in all capital letters.
Installing OLE DB Driver for SQL Server as a dependency
It's important not to uninstall OLE DB Driver for SQL Server until all dependent applications are uninstalled. To provide users with a warning that your application depends on OLE DB Driver for SQL Server, use the APPGUID install option in your MSI, as follows:
msiexec /i msoledbsql.msi APPGUID={0CC618CE-F36A-415E-84B4-FB1BFF6967E1}
The value passed to APPGUID is your specific product code. A product code must be created when using Microsoft Installer to bundle your application setup program. The APPGUID option requires running the installer from an elevated Command Prompt.
