Problem with MSCOMCTL Common Control - Tree View Control after Windows Security Update KB2597986

August 2012

Symptoms

Tree View Control is used in an Access 2010 application

  • in design view of a MS Access 2010 form which uses the tree view control the properties of the control are not displayed and cannot be set

  • in VB code editor event procedures of the Tree View control are not displayed correctly in the drop down listbox

  • at Access runtime events (click, expand,....) are not raised (because of above problem)

the previous version 6.1.98.18 worked fine.

Solution

Windows Security update KB2597986 copied version 6.1.98.34 of MSCOMCTL.ocx to the PC.

32 bit Windows: C:\Windows\System32\MSCOMCTL.OCX

64 bit Windows: C:\Windows\SYSWOW64\MSCOMCTL.OCX

reregister thie new MSCOMCTL.ocx in Windows by using regsvr32

regsvr32 -u C:\Windows\System32\MSCOMCTL.OCX

regsvr32 C:\Windows\System32\MSCOMCTL.OCX

just to make sure do the unregister first


Hope that helps and Thank you, Microsoft!
