Each time when I try to open Microsoft Office 2007 it runs setup on start. It runs the same again and again. I am not able to understand the reason behind it. I thought this will be fixed automatically so I left it as it was. But it is almost 2 months now. I am using Office occasionally. My Windows is also updated. But still the setup never ends. What can be the reason behind this. Can anyone tell me how can I completely block this setup.
