Automation error


This error is as a result of Microsoft Security update MS12-060  released August 2012

This update has caused a problem with an Office dll file  MSCOMCTL.OCX used by Excel to display controls in forms.


Re-register the MSCOMCTL.OCX file.

1. Open the Command Prompt (DOS Window) with admin rights (right-click – Run As Administrator)

2. Type the following:

regsvr32.exe /u C:\Windows\System32\MSCOMCTL.OCX

hit Enter

3. Then Type

regsvr32.exe C:\Windows\System32\MSCOMCTL.OCX

hit Enter

You will need to subsitute the system32  folder with sysWOW64 in the above commands

i.e.  regsvr32.exe /u C:\Windows\sysWOW64\MSCOMCTL.OCX

      regsvr32.exe C:\Windows\sysWOW64\MSCOMCTL.OCX


If this does not work you may have to roll-back to an earlier version of the MSCOMCTL.OCX file. Please follow the steps outlined here:
