Windows 7, 32 bit - MSCOMCTL.OCX "could not be loaded"

Just purchased a new PC Windows 7 32 Bit (not SP1).

Installed Visual Studio 6 Enterprise Editon, with no problems. (Ran the install as 'Administrator'). Applied SP6 also no problems.

When trying to open a Project using MSCOMCTL.OCX (in this case a ListView) I am seeing "MSCOMCTL.OCX could not be loaded". I've Googled around and searched but can't find a solution that works. I've un-registered and re-registered the Control but still see the same Error.

Worse still, if I create a new Project and add MSCOMCTL.OCX from the Project -> Components Menu, draw a ListView on the Form and then use the Object Browser to examine the Properties etc., VB6 Crashes.

Any ideas ?

Doog....same issue, same ocx (I think) awhile back. I copied the ocx form sys32 to 'my' directory (anyone under my profile), added THAT copy of the ocx to the project (browsed when adding ocx), and it worked. Only happened once..don't even remember which project. AND, as you said, "ANY ideas?" :-)

Perhaps, the problems arise because you have installed VS6.0 EE in an inappropriate way.
With my VS6 Installer tool I have installed on Windows 7 32/64 bit in the Home Premium, Professional and Ultimate with or without SP1.

I use juts VS6.0 EE on Windows 7 64bit (no SP1): no problem here! :thumb:

Wrong:

This is a protected Windows system component and has been for a long time. Windows File Protection was vastly improved starting in Vista, which means that it is much harder to mess up than with the old System File Protection in Win2K, Me, and XP.

So that means it is tough to "break" this OCX now. It probably won't even stay unregistrered if you try to. Windows should come along and shovel up the mess you leave like those guys who follow the elephants in a parade.

Sorry about that, I knew better. This library is not supplied by Windows.


What I suspect has occurred, and this isn't a good sign (what the heck are you running on that system?) is that your VB6 design-time licenses are corrupted. In your case this may just have been the result of a silent failure during the installation process. The registry doesn't "just break" contrary to what people may think.

If this is the problem there may be an easy fix, and one that hurts nothing to try anyway. See:

I just ran the Setup with elevated privileges ("Run As Administrator"), no problems were reported, the Installation just went on OK.

@Sam: Tried that, still get the same problem. VB Crashing when using that OCX in a new Project is my major concern. It allows me to add the Control and draw the ListView on them Form with no problems.

Did you run both phases of the install elevated? Normally there's a first run and a reboot, then when the second phase starts after booting you need to kill that and run it elevated.

Ouch. That sounds like a different problem from design-time licenses. But I'd try that fixup utility anyway just for grins.

Tried that, makes absolutely no difference it reports that "Enterprise Design Licenses Have Been Installed Successfully".

As to what's running on the System - nothing. It's a 'virgin' system with Visual Studio and Microsoft Office 2000 installed and that's about it (apart from Microsoft Security Essentials, which was installed after the problems I'm experiencing)

---

Ah, no I didn't do that. Thanks, I'll give it a try.

Really seems odd that only that one OCX would be impacted by whatever has gone wrong though.

Hmm, what about the issues discussed in:

VB6 IDE cannot load MSCOMCTL.OCX after update KB 2687323

Specifically this part:

Quote:

---

The difference is a nasty line in my vbp stating "NoControlUpgrade=1" which controls the "Upgrade ActiveX Controls" checkbox in project properties. When you have the check ticked, this line does not appear in vbp and it silently upgrades the OCX to 2.1. When it is unchecked (i.e. it is 1) you cannot load the project

---

Interesting, I looked at the Project File which had

Code:

---

Object={831FDD16-0C5C-11D2-A9FC-0000F8754DA1}#2.1#0; MSCOMCTL.OCX

---

changing that to

Code:

---

Object={831FDD16-0C5C-11D2-A9FC-0000F8754DA1}#2.0#0; MSCOMCTL.OCX

---

solved the problem with that Project.

There's no "NoControlUpgrade=1" in the vbp file

However, I'm still crashing VB in a new Project after adding MSCOMCTL.OCX and attempting to use the Object Browser.

The problem I met before,after uninstall a software. Try to reinstall VB6/SP6.

Here's one last idea.

Go into the folder where MSCOMCTL.OCX is (should be System32) and look for MSCOMCTL.OCA, remove that file (or if paranoid rename it .BAK etc.) and then try starting a new VB6 project and MSCOMCTL.OCX and using it.

@ Doogle,

What happens if you updated Win7 to SP1?

Thanks for your help, I did as suggested but it didn't make any difference.

I guess you were right and there's been a 'silent' failure during the install so perhaps I'll just remove and re-install with UAC turned off and see if it makes any difference. I don't know if it's related but when I try to install Office 2007 the Setup comes up with a "Setup has stopped working" message and aborts. That might be something to do with already having Office 2000 Pro and Office 2003 Standard installed. (Don't ask why!)

Have to go back to a 'clean machine' and start over.

I gues that'll be another bag of worms. It's currently in the process of installing 134 Security Updates (over 500 Mb of them). I thought that W7 was 'secure' - makes you wonder whether it's fit for purpose, or 'Security Update' is just a 'catch-all'.

Well, performed a re-install on a 'clean machine' and the problem still exists.

The stupid thing is that I can use a ListView OK but if I try to look at MSComctlLib in the Object Browser VB crashes.

Coincentally, yesterday I tried setting a ListView's AllowColumnReorder property to True on a simple project. As soon as
I clicked on a columnheader to drag it, the program crashed, both in the IDE and compiled, with and without Upgrade AX Controls checked.
(BTW XP Sp3, VB6 SP6).

After googling for a while I noted that some users downloaded a previous version of the OCX, which seemed to fix
their problems, but I don't really want to go that way. Hoping someone comes up with a solution.

I met this problem before. The reason is that I installed then uninstalled a poor written software which used MSComctl.ocx. I uninstalled/installed VB6/SP6, the problem remained. Then I manually renamed C:\windows\system32\mscomctl.ocx and put new mscomctl.ocx from my vb6/sp6 installation package and registered MSConctl.ocx by Regsvr32 in DOS command window. Problem is resolved.

I attached mscomctl.ocx info for your reference.

Attachment 95439

BTW, http://www.microsoft.com/en-us/downl....aspx?id=10019
fixed the ColumnReorder problem for me. Not sure if it will fix the problem for the OP.

For completeness, the previous version was 6.1.97.82 and the downloaded version now reads 6.1.97.86

I installed VS6 with my VS6 Installer tool and this does not happen.
In fact I have no problems of any kind, nor with Windows 7 or Windows 8.

I have 6.1.97.82 version.

Have you tried my tool VS6 Installer?

Hi Forum,

I'm having the same problem with a VB6 project which was compiled on the 8th of March this year. Now, whenever I open the vb6 project I get the annoying message:

Quote:

---

'C:\Windows\SysWOW64\MSCOMCTL.OCX' could not be loaded--Continue Loading Project?

---

I'm running Windows 7 64 bit. Everything worked well on the 8th of March 2013. But to day, no chance.

I've checked the object version in the .vbp-file and it is set to 2.1 since months:

Quote:

---

Object={831FDD16-0C5C-11D2-A9FC-0000F8754DA1}#2.1#0; MSCOMCTL.OCX

---

Running the .exe file works fine. In the Process Explorer I see that the .exe loaded the C:\Windows\SysWOW64\MSCOMCTL.OCX.

I have no clue why I can't use (add the OCX in the Project > Components ... > Components Dialog > Microsoft Windows Common Controls 6.0 (SP6) but the exe works!

Things I tried without success:

• Unregistering, Registering did not solve the problem.
• Installing VB6 SP6 did not solve the problem.
• Using other version of the MSCOMCTL.OCX
• Changing the object version in the .vbp-file

I don't want to restore a System Restore Point before 8th of March though...

Any ideas are appreciated.

Don't know if it's the same thing you're talking about but I ran into similar trouble and had to uninstall IE10 to solve it:

http://www.vbforums.com/showthread.p...stered-problem

I could solve my problem: after I checked the updates newer than 8th of March 2013 I googled for the specfic update and mscomctl.ocx - and guess what! Yes, I found the following post. It states uninstalling IE10 would solve the problem.

I unstalled IE10 and voilà, everything worked like a charm!!!!!!!

Oh g*d d*mn M$!!! Since 1990 I am a business and private client of your products... but from now on you will surley understand I won't pay anymore for your products!

Odd that IE-10 would impact ListView control installation.
But, if that does the trick, great.

We had a very similar thing occur installing Microsoft Office 2010 last week. We ended up re-registering the control.

Amazing that this problem is still alive and kicking, and it took me several hours to solve it for me - thanks to all above for input and ideas.

From what I can make out, it seems the problem is linked to the special security measures in windows 8 (maybe earlier as well) and linked to how the explorer searches the indicated folders.

For me the problem was with the MSCOMM32.OCX file. I downloaded it into System32 folder as everyone suggested, ran the regsrv32 but got error messages that it could not find the file. The file was also not visible via the Project>Add References section of VST 2013 - although other .ocx files were visible.

After checking one of these other files, it seems that the security has a special user called "TrustedInstaller" and my file I copied did not have this user defined. It was also not possible to actually assign this user, so I was stuck.

Following what some others had earlier suggested I removed the file from the system32 folder and copied it instead into my Visual Studio 2013 folder (i.e. in my case: c:\users\keith\documents\Visual Studio 2013) and finally now the file could be seen from VST 2013, via: Project, Add Reference, and then clicking on browse and going to the folder. However the file would still not load.

In order to solve this I had to register the ocx using Regsvr32 on a command line (Admin) prompt, but it still tricky since I had to navigate the way to the above folder (using cd commands) before the regsvr32 command finally worked.

After this the ocx file was loaded into VST2013 (Project, Add Reference, Browse or also now visible as Microsoft Comm Control 6.0) and all that was now left was to prefix my MSComm assignment in VST2013 (VB) with MSCommLib.MSComm and finally the error was gone....

So (for the record and hope that someone else might benefit and save wasting hours) to summarise the procedure I successfully used...

1. Copy the MSCOMM32.OCX file to your Visual Basic Studio 2013 folder
in my case: c:\users\keith\documents\Visual Studio 2013

2. Open a Command Prompt (Admin) and navigate your way to your visual basic studio 2013 folder,
in my case cd c:\users\keith\documents\Visual Studio 2013
maybe you have to do this in steps depending on how long your path name is (limitations in the CMdLine prompt), i.e.
in my case:
cd c:\users
cd keith
cd documents
cd Visual Studio 2013


3. run the RegSrv32 command from your new current directory (the visual studio 2013 folder)
in my case: RegSrv32 MSCOMM32.OCX
after this works you can quit the command prompt window.

4. go back to VST2013 and assign the reference
Project, Add Reference, COM, Type Libraries and the scan down to "Microsoft Comm Control 6.0" and select in the check-box and click OK, or
Project, Add Reference, Browse, the click the Browse button and navigate to your visual studio 2013 folder and check the MSCOMM32.OCX file, the click OK.

5. Rerun the build/debug (F5) and check the error is gone. If not you might need to prefix the MsComm definition, i.e.
in my case: Dim WithEvents MSComm1 As MSCommLib.MSComm

in my case the above worked successfully in the build process, although I am a long way away from actually running the code at the moment, but nothing yet to indicate it should not work.....

Don't gravedig old threads.

Your MSComm32.ocx problem is unrelated to topic of this thread anyway.


This is not a free OCX. If your version and edition of Visual Studio included a license for its use then it should already have been installed or a separate installation package provided for it.

See You receive an error message "You do not have a license to use this control" when you use Visual Basic 6.0 controls in Visual Studio 2005 or in Visual Studio .NET

However it isn't clear whether or not later versions of VS include the required controls and licenses to use them.


It has nothing to do with "how explorer searches folders" and if you don't know about TrustedInstaller you are incompetent to write programs for Windows.

Wow...that was some tough love :eek:

Well dead horses can only be beaten so much before you hardly have dog food left.

These post-XP topics were throughly documented for programmers back in 2006 in web pages, multiple downloadable documents, PowerPoint presentations, videos, etc. Microsoft had an entire web site devoted to the topic. Since then we're forced to repeat the information again, and again, and again...

It is now 2015 and we should be spared this. The vestiges remain in rewritten articles on MSDN for those who open their eyes.

Had VB6 IDE running well on W8.1 and W7, but new install on W7 on TWO new machines refused to register MSCOMCTL.OCX and one other OCX. After many re-installs, re-registers, re-boots (yuk) all strangely to no avail finally removed MS Internet Explorer 11 (add/remove examine update/uninstall) cleared up EVERYTHING - thanks for all the hints.

Oddly primary computer has IE 11 installed together with VB6/VS6 and has not problem with this.

Had this issue when IE10 was installed via automatic updates.
Maybe similar issue with IE11.
The final (correct) fix (in lieu of uninstalling IE10) was:

To fix run elevated (Admin) command prompt:

cd C:\Windows\SysWOW64\
regtlib msdatsrc.tlb

x86
---
cd C:\Windows\System32\
regtlib msdatsrc.tlb
