Missing file: wordret.msi on Microsoft Office 2000

[WarRen!]

I am facing issue with Microsoft Office. It is constantly giving missing wordret.msi error on the screen. I cannot add SP3 updates on my system. I am using Office 2007. I have the installation CD also. I performed a repair setup but still there is some issue with missing file. Is there a way to fix the same.Thanks.

It sounds like there may have been at one time a copy of MS Works suite or Word installed. Use Start=>Search on your hard drive to see how many instances of (not shortcuts to) Winword.exe it locates. You may want to use the MS Installer Cleanup utility to remove the tracks of a separate MS Word installation from the registry and then to repair the Office installation. http://support.microsoft.com/kb/290301/en-us?FR=1. I have tried everything suggested and nothing has fixed the problem: Windows configures Microsoft Word 2002, then I get error 1706, then it asks to install Microsoft Works Suite 2002 disk 1, then it asks for Word 2002 and now it asks that I install Windows XP Professional CD even though I don't have that on my computer (I have Home Edition).
