Outlook 2007 running under Windows 7 fails with exception code 0xc0000005

A couple of days ago Outlook 2007 runing in Windows 7 Professional SP1 began failing whenever it trys to open a separate window. For example, I can turn on the reading pane view and see an email. But when I try to open the email, reply to or create a new email I get the "searching for a solution" dialog and Outlook crashes.

I have done the following:
 - Run detect and repair
 - Run scanpst and repair any problems
 - Create  new Outlook profile
 - Uninstall Windows Live
 - Uninstall and reinstall Office 2007
 - Apply all service packs (Windows 7 and Office)
 - Scan for Viruses (AVG) and Malware (Malwarebytes)
 - Search the registry at local machine and current user for non-Microsoft addins (none registered)  

Outlook runs in safe mode so it looks like some kind of addin issue. Any ideas?

Try renaming the outcmd.dat so that Outlook recreates it.  This has fixed the same problem for other people.


Also try disabling and add-ins and see if that helps.
Looks like you got some chances\hotfix to update the Outlook clients?

> either the below or any other suitable latest Outlook updates?

>> Is this issue happening only on few machine or for most of the clients?
