I am having Windows 2008 Server x64 OS. Now in some of the system that are in network Office 2007 is not working. It suddenly stopped. I did not made any recent changes in the system and I am still not able to figure out how this happened. I tried to remove it, so that I can put it back together. While removing the error I receive setup has stopped working. I cannot get rid of it now.The error was about some packages that are used for Office removal. I tried to run the setup over it and got error 1402. About some unknown registry key. How can I get this install back again.
