Support Statement for Visual Basic 6.0 on Windows
Note
The support policy below has been updated with Windows 10 version 20H2 support information.
Executive summary
The Visual Basic team is committed to "It Just Works" compatibility for Visual Basic 6.0 applications on the following supported Windows operating systems:
- Windows 11
- Windows 10
- Windows 8.1
- Windows 7 SP1
- Windows Server 2022
- Windows Server 2019
- Windows Server 2016
- Windows Server 2012 R2
- Windows Server 2008 R2
The Visual Basic team’s goal is that Visual Basic 6.0 applications continue to run on supported Windows versions. As detailed in this document, the core Visual Basic 6.0 runtime will be supported for the full lifetime of supported Windows versions (https://learn.microsoft.com/lifecycle/faq/windows). The support bar will be limited to serious regressions and critical security issues for existing applications. For additional information and product documentation, see the Visual Basic 6.0 Resource Center.
Technical summary
Visual Basic 6.0 is made up of these key deliverables:
- Visual Basic 6.0 IDE (Integrated Development Environment).
- Visual Basic 6.0 Runtime: the base libraries and execution engine used to run VB 6.0 applications.
- Visual Basic 6.0 Runtime Extended Files: selected ActiveX control OCX files, libraries, and tools shipping with the IDE media and as an online release.
The Visual Basic 6.0 IDE
The Visual Basic 6.0 IDE is no longer supported as of April 8, 2008. Additionally, both the Windows and Visual Basic teams have tested Visual Basic 6.0 IDE on Windows Vista, Windows 7, Windows Server 2008, Windows 8, and Windows 8.1 to understand and mitigate (if appropriate) compatibility issues on 32-bit versions of Windows (see the 64-Bit Windows section below for further information about 64-bit systems). This announcement does not change the support policy for the IDE.
The Visual Basic 6.0 runtime
The Visual Basic 6.0 runtime is defined as the compiled binary files originally included in the redistribution list for Visual Basic 6.0. These files were marked as distributable in the original Visual Basic 6.0 license. Examples of these files include the Visual Basic 6.0 runtime library (msvbvm60.dll), controls (i.e., msflxgrd.ocx) along with runtime support files for other major functional areas (i.e. MDAC).
The runtime is divided into the three groups:
Supported runtime files -- Shipping in the OS
Key Visual Basic 6.0 runtime files, used in the majority of application scenarios, are shipping in and supported for the lifetime of supported Windows versions. This lifetime is five years of mainstream support and five years of extended support from the time that a given version of Windows ships. These files have been tested for compatibility as part of our testing of Visual Basic 6.0 applications running on supported Windows versions.
Note
All supported Windows versions contain a nearly identical list of files, and the redist requirements for applications containing these files should be nearly identical. One key difference is that
TriEdit.dllwas removed from Windows Vista and later versions.Supported runtime files –- Extended files to distribute with your application
This extended list consists of key controls, libraries, and tools that are installed from the IDE media or from Microsoft.com to the developer machine. Typically, the VB6 IDE installed these controls to the developer machine by default. The developer still needs to redistribute these files with the application. The supported version of the files is available online on the Microsoft Download Center (https://go.microsoft.com/fwlink/?LinkID=142927).
Unsupported runtime files
Some files either have fallen out of mainstream support or were never included as a part of the runtime redist (e.g., they were included in the
\Toolsfolder on the IDE media to support legacy VB4/VB5 applications, or they were third-party controls). These files are not supported on Windows; instead they are subject to whatever support agreement applies to the media they were shipped with. This implies no warranties around support and servicing. In some instances, later versions of these libraries are supported. Details on backward compatibility or migration to supported versions are provided below.
For specific details on the files included in each support group see the Runtime Definition section below.
The Visual Basic 6.0 support lifetime
Supporting and/or shipping Visual Basic 6.0 runtime binaries on supported Windows versions does not change the support policy for the Visual Basic 6.0 IDE or Visual Studio 6.0 IDE as a whole. Those products moved out of extended support on April 8, 2008.
Details on the support lifecycle of Microsoft products can be found at https://support.microsoft.com/gp/lifepolicy. As a part of this support lifecycle, Microsoft will continue to support the Visual Basic 6.0 runtime on supported Windows versions for the support lifetime of those operating systems. This means, for example, that the Visual Basic 6.0 runtime will be supported on Windows Server 2003 until June, 2008 for Mainstream Support and June, 2013 for Extended Support.

Note
VB6 runtime support is limited by the Windows support lifecycle. For example, if the target OS is in Extended support, VB6 cannot have a higher level of support than Extended support. The Windows support lifecycle fact sheet contains additional lifecycle information about previous and current Windows versions.
64-Bit Windows
Visual Basic 6.0 runtime files are 32-bit. These files ship in 64-bit Windows Operating Systems referenced in the table below. 32-bit VB6 applications and components are supported in the WOW emulation environment only. 32-bit components must also be hosted in 32-bit application processes.
The Visual Basic 6.0 IDE has never been offered in a native 64-bit version, nor has the 32-bit IDE been supported on 64-bit Windows. VB6 development on 64-bit Windows or any native architecture other than 32-bit is not and will not be supported.
Windows 7 SP1, 8.1, 10 & 11
Since the initial release of this support statement, the Windows 10 and Windows 11 operating systems have been released. This document has been updated to clarify Microsoft’s support for VB6 on Windows.
The VB6 runtime will ship and will be supported in Windows 10 and Windows 11 for the lifetime of the OS. Visual Basic 6.0 runtime files continue to be 32-bit only, and all components must be hosted in 32-bit application processes. Developers can think of the support story for Windows 10 as being the same as it was in prior versions.
Windows Server 2008 R2, 2012 R2, 2016, 2019, and 2022
Since the initial release of this support statement, the Windows Server 2008 R2, 2016, Windows Server 2019 and Windows Server 2022 operating systems have been released. This document has been updated to clarify Microsoft’s support for VB6 on Windows Server.
The VB6 runtime will ship and will be supported in Windows 10 and Windows 11 for the lifetime of the OS. Visual Basic 6.0 runtime files continue to be 32-bit only, and all components must be hosted in 32-bit application processes. Developers can think of the support story for Windows 10 as being the same as it was in prior versions.
Visual Basic 6.0 runtime usage inside VBA and Office
Visual Basic for Applications, or VBA, is a distinct technology commonly used for application automation and macros inside of other applications, most commonly inside Microsoft Office applications. VBA ships as a part of Office and therefore the support for VBA is governed by the support policy of Office. However, there are situations where VBA is used to call or host Visual Basic 6.0 runtime binaries and controls. In these situations, Visual Basic 6.0 supported runtime files in the OS and the extended file list are also supported when used inside of a supported VBA environment.
For VB6 runtime scenarios to be supported inside VBA, all of the following must be true:
- The host OS version for VB runtime is still supported.
- The host version of Office for VBA is still supported.
- The runtime files in question are still supported.
Visual Basic Script (VBScript)
VBScript is unrelated to Visual Basic 6.0 and this support statement. However, VBScript is currently shipping as part of Windows 7, Windows 8.1, Windows 10, Windows Server 2008 including R2, Windows Server 2012 including R2, and Windows Server 2016 and is governed by the OS support lifecycle.
Third-party components
Microsoft is unable to provide support for third party components, such as OCX/ActiveX controls. Customers are encouraged to contact the original control vendor for details on support for those components.
Reporting issues with VB 6.0 applications running on Windows
Developers planning to use Visual Basic 6.0 with one of the listed Windows operating systems should install that operating system and begin application compatibility testing using original application acceptance testing.
If you find an issue with your Visual Basic 6.0 application running on one of the listed Windows operating systems, please follow your normal support channels to report the issue.
