Remove Dell Support and Dell Solution Center

I am trying to remove the above two programs.  When I go to Add/Remove on my Control Panel and try and remove them, I get the following message:

[For Dell Support]:

"The feature you are trying to remove is on a CD-Rom or other removable disk that is not available.  Insert the 'Dell Support' disk and check OK' 

[Note: there is a window below that labeled 'Use Source' which has a '1' in it; I assume this is where it's trying to find the removable disk; before inserting one of the CD's below I have changed it to D;\ ]

The labels on the removable CD's which came with my computer are as follows:

1. APPLICATION ALREADY INSTALLED ON YOUR COMPUTER; For reinstalling Dell Tolls System Software Contents: - Antivirus software; - Support Software; - Multimedia software; - Internet software

2. DRIVERS AND UTILITIES ALREADY INSTALLED ON YOUR COMPUTER; Dell Dimension Resource CD; Contents: -Device drivers; - Diagnostics and utilities; - Computer documentation

3. DRIVERS AND UTILITIES ALREADY INSTALLED ON YOUR COMPUTER; For reinstalling V.9X (Capable)/56K Date/Fax Modem; Software for Microsoft Windows; Contents: - Drivers; - Diagnostics and utilities; - Online documentation; - Modem on Hold

4. OPERATING SYSTEM ALREADY INSTALLED ON YOUR COMPUTER; Reinstallation CD; Microsoft Windows XP Professional Including Service Pack 1a

5. DELL E172FP COLOR MONITOR USER DOCUMENTATION

When any of these CD's are inserted into the D:\ drive I get the following error message:

The path "d:\Sherman.MSI cannot be found. Verify that you have access to this location and try again or try and find the installation package Sherman.MSI in a folder from which you can install the product  Dell Support."

I'm not sure where to go from here.  I can't find the file "Sherman.msi" on any of the removable disks or on my c drive.  I think I don't have the correct removable CD but I was careful to save *everything* when I bought this computer.  If I don't have the correct one, where can I get it?  Or is it some other sort of problem?

I have a similar problem when trying to remove "Dell Solution Center".  However, it appears to be looking for a file name "DSC.MSI"  Any ideas or suggestions?
