Hi,
My suggestion would be to repair the Outlook 2007 install first.
Also make sure you have the .Net Interop assemblies intalled for Outlook 2007.
In Control Panel | Add Or Remove Programs - select your Office 2007 and click Change. In Microsoft Outlook make sure you have the ".Net Programmability Support" checked for installation to local machine.
