Quite often one of the major problems with the migration to the 64bit-Edition of Microsoft Access is the Microsoft TreeView Control included in the Microsoft Windows Common Controls library. For a very long time this control was not available for 64bit.

Prologue – (Un)Availability of the 64bit TreeView

In the early days of 64bit Office/Access there was increased confusion about this topic because apparently Microsoft included the Common Controls in the 64bit installation, but that were the 32bit Common Controls, which did not work in 64bit applications.

After years of countless support request and complaints, Microsoft finally decided to release a 64bit edition of the Microsoft Common Controls particularly for the use with Microsoft Office. This was released in the Update 1707 of July 27 2017 (Build 8326.2058).

As there still is ongoing confusion on how to install and use the 64bit Edition of the Microsoft Common Controls, I decided to investigate the issues and write down my findings.

No 64bit TreeView with Access 2013 (and 2010)

I started my investigation with an installation of Microsoft Access 2013 64bit in Windows 8.1 (64bit). I’m very certain that the operating system is not relevant in this context and it will not matter whether this is done on Windows 7, 8 or 10.

With a default installation of Microsoft Access 2013 64bit there is neither a MSCOMCTL.OCX file in C:\WINDOWS\SysWOW64\ (this is the system directory of the 32bit subsystem!) nor in C:\Windows\System32 (the default 64bit system directory). If I try to insert an ActiveX Control into an Access form there is no Microsoft TreeView Control available in the list of installed ActiveX Controls.

The 64bit TreeView with Access 365 (and 2019)

Then I installed the 64bit Edition of Microsoft 365 Click-to-Run (C2R). At the time of writing, I got the Version 2003 of Access 2016/365. Installing this did not make any difference regarding the MSCOMCTL.OCX file in the Windows system directories mentioned above.

We must be aware of the fact that the C2R-Editions of Office are installed into a semi-virtualized environment (sandbox). For a 64bit Office installation, all files that are not immediately a part of Office will not be installed in the usual, global system directories but in the directory C:\Program Files\Microsoft Office\root\vfs (vfs = Virtual File System). The System subdirectory in the above directory now contains our desperately needed MSCOMCTL.OCX file.

After starting my newly installed Access 2016 and creating a new form, I’m immediately able to insert a TreeView Control into this form. The TreeView visually appears “normal”, displays the sample nodes and a small bit of test code I created, works also as expected, including the event handling.

Let me know exactly what you wanted from the article or the “FCO” tag, and I’ll give a precise, useful answer.

The air in the "TechWorld" server room was thick with the hum of fans and the smell of ozone. Nana Janashia, known across the digital realms as the architect of clarity, stood before a holographic console. Her mission: to transform a ragtag group of aspiring engineers into a fleet of elite DevOps warriors.

"The old ways are crumbling," Nana said, her voice steady. "Manual deployments and siloed code are the ghosts of the past. Today, we build the pipeline." Phase 1: The Containerization

The trainees started in the Docker shipyards. They learned to package their heavy applications into sleek, lightweight containers. "If it doesn't fit in the box, it doesn't sail," Nana warned. One student, Leo, struggled with a bloated image until Nana showed him the art of multi-stage builds—shaving gigabytes off his payload in seconds. Phase 2: The Orchestration

With their containers ready, the team faced the Kubernetes nebula. It was a chaotic swirl of pods and nodes. Nana guided them through the YAML scrolls, teaching them how to command the cluster so that if one pod fell, two more would rise in its place. "Self-healing isn't magic," she smiled, "it's architecture." Phase 3: The Infinite Loop

The climax came at the CI/CD bridge. The goal was a legendary feat: a "Zero-Downtime Deployment." As the trainees linked GitLab, Jenkins, and Terraform together, the pipeline began to glow. Code flowed like water, tested by automated sentries and deployed into the cloud without a single stutter in service.

As the bootcamp concluded, the trainees didn't just have certificates; they had the "DevOps Mindset." They looked at the sprawling infrastructure of TechWorld and no longer saw a mess of cables—they saw a living, breathing, automated symphony.

The bootcamp focuses on teaching not just specific tools, but the underlying concepts and how they integrate into a complete Software Development Life Cycle (SDLC).

Self-paced video lectures, illustrated handouts, and hands-on Git projects.

Students complete over 24 real-life projects to build a professional portfolio.

Alex sat at his desk, staring at a tangle of manual deployment scripts that felt more like a trap than a workflow. Every "push to production" was a gamble, a caffeine-fueled prayer that nothing would break. He knew there was a better way—a world of automation, scalability, and seamless pipelines—but he was stuck on the outside looking in. Then he discovered the TechWorld - DevOps Bootcamp by Nana

From the first module, the fog began to lift. Nana didn't just explain tools; she bridged the gap between "code" and "infrastructure." Alex started with the fundamentals of

, containerizing his messy apps into neat, portable packages. He moved on to Kubernetes

, learning to orchestrate those containers like a conductor leading a symphony. Through the bootcamp's hands-on approach, he built a robust CI/CD pipeline

from scratch. He watched, mesmerized, as his code was automatically tested, built, and deployed to the cloud. The "fear of the push" vanished, replaced by the quiet hum of Infrastructure as Code (IaC) using Terraform and Ansible.

By the end of the program, Alex wasn't just a developer anymore; he was a DevOps engineer. He returned to his team not with more scripts, but with a philosophy of efficiency. At TechWorld, he didn't just learn how to use the cloud—he learned how to master it. tweak the tone

Unlike theoretical courses that focus heavily on definitions, Nana’s bootcamp is designed with a "learning by doing" philosophy. The curriculum covers the entire DevOps lifecycle, typically structured around the following pillars:

The "-FCO-" tag implies a complete, hands-on experience. Here is what distinguishes this bootcamp from a simple video series:

Redistribution to Access 2013, 2010 and early version of Access 2016

If I try the same in old Access 2013 installation, I still cannot insert the TreeView controls, as it is still missing from the list of ActiveX Controls. Opening the database, I created with Access 2016 earlier, and then opening the form with the TreeView resulted in in the error “There is no object in this control.”. – I was expecting this due to the Office 2016 sandbox.

The logical next step would be to copy the OCX file to the global System32 directory and register it there.

So, I copied the MSCOMCTL.OCX file from the Office virtual files system into the C:\Windows\System32 folder. I then ran cmd.exe as Administrator and executed

C:\Windows\System32\regsvr32 /i C:\Windows\System32\MSCOMCTL.OCX

Unfortunately, this failed with the error message “… the call to DllRegisterServer failed with error code 0x8004005.” – Well, this might have happened because there are some dependencies of MSComCtl.ocx that in the Office-VFS\System folder, which I did not copy.

Next, I tried to copy all the files from Office-VFS\System to a new folder and run regsvr32 for the OCX in that folder. – No luck, the error message quoted above persisted.

I’ve got no clue what the problem is here. Maybe I missed a step. If you see my mistake, please let me know!

Hacking the Redistribution

The normal and recommended way to register a DLL or OCX on any system is to use regsvr32.exe as I tried above. However, in the end for most ActiveX/COM controls and components it boils down to adding some keys and values to the Windows Registry.

As a workaround to the dead-end with using regsvr32 to register the OCX, I started RegEdit and looked for the relevant Registry keys and values for the TreeView Control of my Office 365 C2R installation.

These are usually in the HKEY_CLASSES_ROOT branch of the Registry and are below the class name (“MSComctlLib.TreeCtrl”) and the class id (=CLSID) (“C74190B6-8589-11D1-B16A-00C0F0283628”) of the control or component. As the C2R-Office is in a sandbox these values are also not in their usual registry path but sandboxed below the path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY.

I then exported these two keys with all their subkeys to.reg text files. I then edited those files and replaced their registry path with the usual base path HKEY_CLASSES_ROOT. After that I merged the edited files with the registry again.

(Reminder: I previously copied the MSCOMCTL.OCX file to C:\Windows\System32\. This is the file these re-imported registry values are pointing to!)

Et voilà! After merging my edited files in the registry, the Microsoft TreeView Control shows up in the list of insertable ActiveX controls in Access 2013! I also quickly tested my small code fragment from above and it worked!

32bit/64bit compatibility?

What if we need to use one and the same database application file in Access 32bit as well as Access 64bit? – If is an accdb (not compiled to accde) you can usually work with one and the same file without a problem. (If you use the Windows API, you need to make sure your API declarations are 64bit compatible.)

What about the TreeView in this situation? If I create a form with a TreeView in Access 2016 64bit where the TreeView control is automatically available, I can open the very same database file with Access 32bit (tried Access 2016/365, Access 2013, and Access 2010) and it works right away.

However, if I try a form with a TreeView control that was created in Access 2013 after applying the above registry hack, I get an error message in Access 32bit (again: Access 2016/365, Access 2013, and Access 2010).

“The expression [AnyEvent] you entered as the event property setting produced the following error: There was an error loading an ActiveX control on one of your forms or reports.”

This usually indicates a problem with binary compatibility between different versions of a control. However, this cannot be the case here, otherwise it should not have worked with the Access-2016-created file.

I guess, I must have missed something in my redistribution hack above. – I’m not really affected by this problem, so I’m not investing more time into fixing this problem. But, again, please let me know if you know the solution to the issue.

The other way round, creating a form with TreeView control in Access 32bit and then using this form in Access 64bit worked without any problems in the default Access 2016/365 installation as well as in Access 2013 with the “hacked” TreeView installation.

Conclusion

Current versions of Access 2016/365 (and probably Access 2019 as well) have a fully compatible MsComCtl TreeView control, which works out of the box.

However, this control is not intended for redistribution on its own, neither technically nor legally. If you need to use it with an older version of Access, you can probably work around the technical limitations using an approach like mine. But this does not solve any potential legal issues. - I’m not aware of any redistribution license for the 64bit MsComCtl.ocx.

If you want to distribute an application using the MsTreeView to users which don’t have an Access version with the 64bit-TreeView, the best option is probably using the Access 365 Runtime, which is receiving updates and thus should also include the 64bit common controls. – Disclaimer: I have not tested the Access 365 Runtime yet.
