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

I agree - a reboot was not required for any of our customers either.

Here's what worked for me:

I just had to make sure that all MS Access 2010 applications were closed then run the following:

For Windows 7 64 bit

regsvr32 c:\windows\sysWOW64\mscomctl.ocx /u

regsvr32 c:\windows\sysWOW64\mscomctl.ocx

For 32 bit

regsvr32 c:\windows\system32\mscomctl.ocx /u

regsvr32 c:\windows\system32\mscomctl.ocx

After re-registering the ocx our custom Access apps worked fine (list control navigation and double-clicks started working again)

I did not have to reboot any of our 84 computers at all.

Unregistering MSCOMCTL.OCX, Rebooting and then Registering MSCOMCTL.OCX fixes the problem, but it is not a clean solution for my customers who are using my Access HR Program and it does me no good at all for prospective customers who are downloading the trial of my program.  It would be great if we could get another update from Microsoft that fixes the issue for both those who have and have not run the updates that caused this issue.

since i also went through **** with this MS update disaster (till i figured out its a windows update issue that alone took me a half a day) i'll share what worked for me,

i tried all kinds of unregister register tricks, i replaced the ocx's with 3 different version, with little to no success.

i had to deal with close 100 workstations version XP, 7, Vista, finally here is what worked for me:

1. if you have tried already other remedies, you may have screwed it up to a point that my solution may not solve it, so what you need to do, run a system restore to the point before the windows update, apply the windows updates again, then try again my solution
2. you need to have a copy of an older version of mscomctl.ocx, in a folder other then the system folder, i had version (6.01.9818) in c:\temp\mscomctl.ocx,
3. i have not verified if it has to be version (6.01.9818) but this is what worked for me, others i don't know
4. after Windows applied the culprit update (which is KB2687441), run the following script, ideally save it in a batch file and run it on all workstation,

if exist %systemroot%\SysWOW64\cscript.exe goto 64

%systemroot%\system32\regsvr32 /u mscomctl.ocx

%systemroot%\system32\regsvr32 mscomctl.ocx

%systemroot%\system32\regsvr32 "c:\temp\MSCOMCTL.OCX"

exit

:64

%systemroot%\sysWOW64\regsvr32 /u mscomctl.ocx

%systemroot%\sysWOW64\regsvr32 mscomctl.ocx

%systemroot%\sysWOW64\regsvr32 "c:\temp\MSCOMCTL.OCX"

exit

5. you should get 3 "successful" dialog boxes confirming the regsvr32 execution.
6. if you get a "unsuccessful" dialog then its a a security issue and you need to run the script as administrator

i hope this will be of help
