Security Update for mscomctl.ocx (KB2597986 MS12-060) August 2012 Updates: Listbox double-click no longer works

After installing the August 2012 round of patches (MS12-060: Vulnerability in Windows common controls could allow remote code execution), an Access 2010 application using the Windows common controls Listbox no longer responds to a double-click.

The update installs MSCOMCTL.OCX 6.1.98.34 dated 6 Jun 2012.

Reverting to the previous version of the file (version 6.1.98.33, variously dated 7 or 14 Feb 2012 solves the problem.

I think this probably applies to Win XP as well.

Anyone else come across this? Any other issues with this update?

We had the problem and the way round it is to unregister mscomctl.ocx, log off, log back on and then register mscomctl.ocx.  The log off stage is important.  Without doing this unregistering and registering doesn't work.

This 'fix' has worked for us on PCs running Office 2003, 2007 and 2010 (Windows 7 64bit, Vista and XP)

    regsvr32 c:\windows\syswow64\mscomctl.ocx worked fine with me. Thanks!

    Yes, we have validated this solution with our customers as well.  Removing the 2.0 and re-registering mscomctl.ocx have solved all of our issues related to this security update.

    Thanks.

     

    Further update - we've found that our fix doesn't work on all PCs.  Where it doesn't we are now using a slight variant on other suggestions posted.

    1. Unregister mscomctl.ocx
    2. Rename mscomctl.ocx as mscomctlNEW.ocx

    3) Copy an old version of mscomctl.ocx (from internet) to system32 or syswow64

    1. Register mscomctl.ocx
    2. Unregister mscomctl.ocx
    3. Delete mscomctl.ocx
    4. Rename mscomctlNEW.ocx as mscomctl.ocx
    5. Register mscomctl.ocx

    Unbelievable - but it seems to work

    Simply unregistering and then  registering the new mscomctl.ocx has never worked for us

    Thanks a lot, I was searching for this solution for a while.

    We have an Access 2003 database used by several PCs on Windows XP.

    I have first updated the reference to MSCOMCTL.OCX in VBA ("References" Menu).

    It worked (listview seemed to be ok in the form) but everytime I was moving the mouse or clicking in the list, I had error messages (Mouse_Move, Item_Click, etc.).

    Finally, this get solved by your solution :

    • unregistering the 6.1.98.34 version
    • registering back the 6.1.98.33 version
    • unregistering the 6.1.98.33 version
    • registering forth the 6.1.98.34 version

    (no need to close the Windows session, no need to reboot Windows.

    After that, no more errors.
