Disclaimer: This control is legacy technology (VB6/ActiveX). It is not supported on modern 64-bit only applications (like Office 64-bit, many browsers, or modern .NET Core apps). It is intended for maintaining legacy Visual Basic 6.0 or MFC applications on 32-bit Windows.
If your application only needs a simple date picker on modern systems, consider replacing the MonthView control with a newer, supported alternative (e.g., Windows API month calendar control or .NET DateTimePicker). Use MSCOMCT2.OCX only as a last resort for maintaining legacy software.
Disclaimer: This guide is for educational and legacy support purposes. Microsoft strongly advises against deploying OCX controls in new development.
The Microsoft MonthView Control 6.0 (MSCOMCT2.OCX) is a 32-bit legacy ActiveX control requiring the VB6 Common Controls package, with installation involving placing the file in System32 or SysWOW64 and registering it via regsvr32. It is not compatible with 64-bit Office, and its registration is necessary for functionality in VBA environments. For official installation files, visit the Microsoft Download Center.

The Microsoft MonthView Control 6.0 (SP4) is a specialized graphical user interface element used primarily within the Visual Basic 6.0 (VB6) and Microsoft Visual Studio development environments. As part of the Windows Common Controls (MSCOMCT2.OCX), it provides developers with a ready-made calendar interface, allowing end-users to view and select dates intuitively. The Role of MonthView in Legacy Development
During the peak of VB6 and early VBA (Visual Applications for Applications) development, the MonthView control was an essential tool for creating user-friendly forms. Unlike a simple text box where a user might mistype a date format, the MonthView control displays a classic monthly calendar grid. It supports features like multi-selection of dates, highlighting the "today" date, and easy navigation between months and years. Challenges with Modern Systems
The primary challenge today is that the MonthView control is a legacy 32-bit ActiveX control. Because it is no longer bundled with modern versions of Windows or Office, users attempting to run older software often encounter errors like "Component 'MSCOMCT2.OCX' or one of its dependencies not correctly registered." Installation and Registration Process
To resolve these issues or to use the control in new projects, a specific manual installation process is required:
Acquisition: The control is contained within the MSCOMCT2.OCX file. This is typically obtained via the Microsoft Visual Basic 6.0 Common Controls update or by extracting it from a Service Pack 4 (or 6) installer.
Placement: On modern 64-bit versions of Windows, the file must be placed in the C:\Windows\SysWOW64 directory. On 32-bit systems, it goes in C:\Windows\System32. microsoft monthview control 60 sp4 download install
Registration: The system must be told the control exists via the Command Prompt (running as Administrator). The command used is:regsvr32 c:\windows\syswow64\MSCOMCT2.OCX
Integration: Once registered, the control appears in the "Components" dialog box of the VB6 IDE or the "Additional Controls" menu in the Excel/Access VBA editor. Security and Compatibility Considerations
While the SP4 version was a milestone for stability, developers should note that ActiveX technology is increasingly deprecated due to security vulnerabilities. Modern web and desktop frameworks (like .NET or React) offer native, more secure date-picker alternatives. However, for the maintenance of "mission-critical" legacy systems, the MonthView control remains a vital, if aging, piece of software architecture.
In summary, the Microsoft MonthView Control 6.0 SP4 is a relic of a highly successful era of rapid application development. While it requires manual intervention to function on modern hardware, its simplicity and effectiveness continue to make it a staple for those maintaining classic Windows applications.
The Microsoft MonthView Control 6.0 (SP4)—typically packaged within the mscomct2.ocx file—is a legacy ActiveX component used primarily in VBA (Visual Basic for Applications) and VB6 environments to provide a user-friendly calendar interface. Although newer service packs like SP6 are more common today, many legacy systems still require the specific SP4 version for compatibility. Understanding the MonthView Control
The MonthView control allows users to select dates from a visual calendar rather than typing them manually into a text box. It is part of the Microsoft Windows Common Controls-2 6.0 library.
Crucial Compatibility Note: This control is a 32-bit component. It will not work with the 64-bit version of Microsoft Office (Excel, Access, etc.), even on a 64-bit Windows OS. If you are using 64-bit Office, you must use a custom VBA UserForm or a third-party add-in as an alternative. Step 1: Download the Required Files
To install the MonthView control, you need the mscomct2.ocx file. It is often included in cumulative update rollups for Visual Basic 6.0.

This control is 32-bit only. It will not function in 64-bit versions of Microsoft Office. If you are using 64-bit Office, you must either switch to 32-bit Office or use alternative custom VBA calendar forms. Download and Installation Steps
Download the Library:The control is part of the Visual Basic 6.0 Common Controls package. You can find the latest rollup from the Microsoft Download Center.
Placement:After downloading, copy the MSCOMCT2.OCX file to the correct system folder based on your Windows version: 64-bit Windows: C:\Windows\SysWOW64\ 32-bit Windows: C:\Windows\System32\
Registration:You must register the library manually using the Command Prompt:
Open the Start menu, type cmd, right-click it, and select Run as Administrator.
For 64-bit Windows, enter: regsvr32 C:\Windows\SysWOW64\MSCOMCT2.OCX.
For 32-bit Windows, enter: regsvr32 C:\Windows\System32\MSCOMCT2.OCX.
You should see a message confirming successful registration. Enabling in Office (Excel/Access): Open the VBA Editor (Alt + F11). Insert a UserForm.
Right-click the Toolbox, select Additional Controls, scroll to find Microsoft MonthView Control 6.0 (SP4/SP6), and check the box. Troubleshooting
