Outlook 2007 won't start in Windows 7

[RPVG]

I have using windows 7 since its beta stages and the current version on my PC is Windows 7 RC Build 7100. I never had any bugs and errors due to which i am still using Windows 7 RC. Now suddenly Outlook stopped working and i get a message saying : [Cannot start Microsoft Office Outlook. Cannot open the Outlook window.] Can anyone tell me what could be done to solve this problem? Outlook 2007 was working flawlessly before...

I think you have to keep updating the Windows 7 RC regularly so that the bugs and flaws keeps getting updated out. Did you recently downloaded some updates which might have caused it? I think its not due to update and due to an update which is not downloaded. Update Office and Windows both and see if that works...

Try to reboot your system and then try running outlook, does it work then? Or may be start Windows 7 in safe mode and run Outlook, there must be something running which doesn't let Outlook to run. Also if this is not solved, you can backup your data and try re-installing Office 2007, there are chances that this bug goes off.
