Outlook 2007 - Cannot open the Outlook Window

I ran into an interesting issue this morning. User is running Windows 7 with Outlook 2007 and when he attempts to launch Outlook he gets an error that says "Cannot Start Microsoft Outlook. Cannot open the Outlook Window." I have attempted to repair Office which failed with the bootstrapper crashing but was able to uninstall Office 2007 and re-install it. The issue still remained even after a full removal and re-install. I deleted the mail profile and OST which also did nothing. The final fix is this: Open a command prompt and navigate to the Office12 directory and run this command "outlook.exe /resetnavpane" Odd that a re-install does not reset it enough...
