Microsoft Office Professional Edition 2003 worst problem

For many days i had this problem.Whenever i paste any words in Microsoft Office Word 2003…a Popup comes saying :

Please wait while Windows configures Microsoft Office Professional Edition 2003

and then it pastes.It is annoying.Each time when i paste,it comes. msiexec.exe runs in the process.I disabled it in services.Then no problem in pasting.I installed a software later,then it asked for windows installer as it is needed.Then once again i enabled it.

So i wanted to stop that popup from coming without disabling msiexec.exe. But that is not possible.Also in control panel, The options - change or remove is not there for Microsoft Office Word 2003. It is like that for many days.I dont know how they disappeared.I dont know what problem it is.

In Microsoft Office Word 2003 under Help option, when i click Detect and Repair…It says Microsoft Office Professional Edition 2003 setup failed

Today i uninstalled Microsoft Office Professional Edition 2003 and reinstalled. Now the problem is too worse.
Now whenever i open Microsoft Office Word 2003 or Yahoo messenger or MSN messenger, that same old popup comes :

Please wait while Windows configures Microsoft Office Professional Edition 2003

Eventhough i cancel that popup, OSE.exe and msiexec.exe runs in the process. So each time i have to end the process OSE.exe and msiexec.exe when i use Microsoft Office Word 2003 or Yahoo messenger or MSN messenger.Its very annoying. :frowning:

Can anyone help ?

I too had this problem with Microsoft office 2003.My copy was fully legit,had a product code which was validated,but it still kept on doing this(only in the last year,I`ve had it for 5 years).One solution would be to buy the latest version of Microsoft Office but not everybody has the cash these days,anyway I got so fed up re-installing it every time,that I binned it and now use Open Office,which is free,and does vitrually everything Microsoft Office does,including reading Microsoft docs and spreadsheets
