Visual Studio 6 Windows Common Controls 6 0 sp6 Windows 7 64 bit

Question

I was asked to help work on a legacy vb6 application for someone  so I decided to toss Visual Studio 6 on my Windows 7 x64 laptop following this guide   It installed fine  and from I can see everything is working except for Microsoft Windows Common Controls 6 0  sp6   Microsoft Windows Common Controls-2 6 0  sp6   Microsoft Windows Common Controls 5 0  sp2   etc  all work just fine  However  when I try to add the Microsoft Windows Common Controls 6 0  sp6  component I get the error      could not be loaded   I could not add an image  so I have uploaded a screen shot to here for anyone wanting to see it exactly     I have tried registering un-registering re-registering MXCOMCTL OCX  MSCOMCT2 OCX  msdatsrc tlb all with no success  I have also uninstalled a known security update that may have caused issues with Windows Common Controls  I have removed IE11  even though reports state IE11 will not cause issues with MSCOMCTL OCX the way IE10 did    I run VB6 EXE in Windows XP SP3 Compatibility mode  With Disable visual themes  Disable desktop composition  and Disable display scaling on high DPI settings  As well as run it as administrator   I have also attempted to open a previous project that utilizes this control  and it fails during load with the same  blank  error as in the screen shot with the following in the generated error log   Line 35  Class MSComctlLib ListView of control lvData was not a loaded control class  Line 223  Class MSComctlLib StatusBar of control Stat was not a loaded control class   So that tells me it isn t a version issue within the  vbp like some suggest  as it happens with new  blank projects as well    I am at wits end  Apparently people have gotten both VB6 and Windows 7 x64 to work properly  with Windows Common Controls  but NOTHING I have tried alleviates my problem  I am hoping someone here may have run into this  or have some ideas as to what is going on

Open Registry Editor using run command regedit.

Locate HKEY_CLASSES_ROOT\TypeLib Key and then did a search for "MSCOMCTL.OCX" and deleted EVERY key that referenced this .ocx file.

Open command prompt (cmd) in Administrator mode. The type the following code,

In 32 bit machine,

cd c:\Windows\System32
regsvr32 MSCOMCTL.OCX
regtlib msdatsrc.tlb
regsvr32 MSCOMCT2.OCX

In 64 bit machine,

cd c:\Windows\SysWOW64
regsvr32 MSCOMCTL.OCX
regtlib msdatsrc.tlb
regsvr32 MSCOMCT2.OCX

just what jay said just delete those registry entries which are pointing to other paths other than on c  windows system32 Those are the culprits of the error I got those errors on my vb6 IDE and after deleting those anomalous registry entries the problem was fixed  works like a charm

I had the  problem whereby VB6 IDE would not load the common controls  Sp6 with VB6 install on W7 64bit  specifically comctrl and msmask  I tried all the solutions proposed using regsrv32  elevated   edited the registry  changing the version number in the vbp etc as proposed by MS and others  All failed  These solutions worked on my other 2 PCS but not this one  Eventually I removed IE11 and all worked properly afterwards  IE10 had never bene installed on thsi PC - we went straight from IE8 to IE11 and have been forced to backtrack to using IE8     I have to say the simple solution above does not address the problem which is that the VB6 IDE will not load the common controls  using the Components menu selection under Project  - you get an error saying Object not loaded  So this will happen  and I proved this to myself  on any project  new or old that try to use theose common controls that will not load    So my suggestion to anyone who has this problem is to try the manual register solution using regsrv32 route  then the edit the vbp to change the version  and if these fail uninstall IE11  and defintely IE10   But this may still not be a 100  solution because if your existing project files   vbp  contain references to the wrong common controls you need to correct that manually - this is where loading a new project  loading the Components you need inside the IDE  then edit the newly create vbp using notepad and copy the version numbers for the common controls to your existing vbp files

While waiting for a reply for ideas here  I had decided to try something  I ran regedit as administrator  navigated to the HKEY CLASSES ROOT TypeLib Key and then did a search for  MSCOMCTL OCX     I deleted EVERY key that referenced this  ocx file   After searching the entire registry  deleting what I found  I ran command prompt as administrator  I then navigated to C  Windows SysWOW64 and typed the following commands   regsvr32 MSCOMCTL OCX regtlib msdatsrc tlb   Upon registering these two files again  everything is WORKING  I scoured the web for HOURS looking for this solution to no avail  It just so happens I fixed it myself after posting a question here    Even though Visual Studio 6 is outdated  hopefully this may still help others

I was having the same difficulty loading my VB 6 project  Here is a sample error message   Class MSComctlLib ProgressBar of control prgExecution was not a loaded control class    This problem was solved by some Microsoft Magic as follows   I opened the Project Components window in my broken project   I clicked on Browse and found the file MsComctl ocx  I clicked on OK   VB 6 then got stuck  the application non responsive    After some time  I ended the VB 6 application using the task manager   Then  magically  when I opened up my VB 6 project to show my programming friend what a POS this project was  all the controls were back  linked as expected   Somehow  something was registered or fixed

Just today I had the  questionable  pleasure to get VB6 code running on Windows   64 Bit  I did come across this thread  but none of the proposed solutions worked for me  Neither worked adding references using the  Project -  References     menu   To get it running  I had to manually modify the VB6 project file    vbp   For all the libraries I had load issue with I had to use the following notation to define as reference  Object  Registry Key  Version 0  LIBRARY OCX Example  Object  FAEEE763-117E-101B-8933-08002B2F4F5A  1 1 0  DBLIST32 OCX  I had not to register any of the libraries  using regsvr32   these were all already correctly registered  I guess why my solution works is that if the  object         notation is used  instead of the  Reference   G        notation  VB Studio is using the Registry Key only and gets rooted to C  Windows SysWOW64 while as the other way ends up looking in C  Windows System32  By the way  IE11 is installed  Whether or not this matters  only Bill G might know  My guess is that my solution works regardless which IE is installed  You just might have to unregister and register the missing libraries as mentioned in this thread   Hope that helps anyone who faces similar issues

My solution was replacing the MSCOMCTL OCX on windows 10 box with one from a Windows 7 box that also had MS Access installed  For some reason  there are different MSCOMCTL OCX 2 0 controls with the same name   I know this sounds crazy  and might not help anyone else  but we have saved this MSCOMCTL OCX with a readme file and it has fixed our new install errors every time   we unregister the current MSCOMCTL OCX that came with Windows 10 box  delete it  and register the old one we have saved

Implementing the two directives already worked for me from within  C  Windows SysWOW64   regsvr32 MSCOMCTL OCX regtlib msdatsrc tlb   It s worth noting that the DOS box should be in Administrator mode   Prior to this  I kept having errors in the vein  Class MSComctlLib TreeView of control tvTreeView was not a loaded control class  and  Class MSComctlLib ListView of control lvListView was not a loaded control class    I am also using Visual Studio 6 on 64 bit Windows 7  with SP6 updates   I was driven here due to the same problem   In my case  I did not need to go through the registry

I believe it may be related to a issue in which Microsoft released a update to the MScomCtlLib which was incorrectly patched by microsoft  causing registry errors   I believe if you follow the advice laid out in   https   support microsoft com fr-fr kb 2597986

I had the same problem running windows 7-64 with VB6   I tried the unregister and re-register solutions above but it did not solve the problem  Then I noticed that in my VB6 Components I had references to both the Microsoft Windows Common Controls -2 6 0 SP6  and Microsoft Windows Common Controls -3 6 0 SP5   I removed the SP5 reference and all now works OK  It seems that -2 6 0 SP6 supersedes -3 6 0  SP5  and when both are present there are two references to the same control  Hope this helps  Steve

I have searched this issue for hours and clicked in hundreds of websites  none of them worked   My final solution    run cmd cd c  Windows SysWOW64 locate to the location  regsvr32 MSCOMCTL OCX   this solves the first one  For the second one    run  cmd cd c  Windows Microsoft NET Framework v4 0 30319 regtlibv12 msdatsrc tlb   done   this may not work for everybody  considering the system version reason  etc
