Configuration process starts every time I open an Office program

Most of the time when I open one of the Office 2007 applications, then it starts the configuration process. It seems to be really a pain for me as I have already removed the trial version of office home and student that was pre-installed on my computer. I have checked that it is removed, is there anyway to sort this problem? Thanks.

It looks the setup is not able to complete due to which you are getting that message everytime on the screen. To fix that I will recommend you to perform a clean installation. You can do that by removing Office and then installing it properly from scratch. And ensuring that the setup is fine there is no problem with the same. It is not complicated at all. If still you are getting the same message you have to change your installation file.
