Thanks for the response and suggestions. I am still unable to open MS Office 2008. I am using Mac OS 10.5.2 and Entourage 12.0.0. Not sure how Leopard was installed. Following your suggestion I applied the latest Apple combo update for Leopard. Rebooted and still could not get into OS with same result as described above. I then reinstalled MS Office 2008. The last step was with the Microsoft Office Set-up Assistant to fill the fields and Continue. This I did but immediately got the Error Report, encountered problems, need to close. After closing could still not get into any MSO 2000 programs and with the same result after rebooting. It is interesting that I was never able to get the screen for registering the software with MS since the above-mentioned message came up. Still stuck. Would appreciate any suggestions.
