I found this with Google.
This is caused by a bug in Microsoft Office. It will happen on some computers and not others, and it depends on the order in which you installed your MS Office products and MS Internet Explorer. We believe it only happens with MS Office 2000, but it may also happen with other versions. It happens because MS Office claims incorrect ownership of some of the core Microsoft programming libraries. The programs producing the error may be based upon built-in Internet Explorer functionality, - it's a direct conflict between different MS products.
Remedy: The work-around is also different on different computers. On some computers if you click "Cancel" the first time, you will never see the message again. On other computers you need to run through the requested installation process to make the message go away. On other computers you may see the message a few times then never again. Most computers will at least not display the message more than once in a single browser session.

I am running Windows XP with Office XP. What I did was create a folder on my hard drive and copied Dellbckp.msi and Data Cab into it. Now when it asks me for the cd, I direct it to this folder. It is not a fix but a work around the annoyance.
I have tried cancel but I get errors. It is strange since it is not a Dell product and it not an install.
