data1.msi

I am trying to uninstall Front Page Server Extensions from my NT server. However, I get an error message that the file data1.msi is not a valid source. I have tried several various versions of this file from various CDs to no avail. I cannot find the original CD our consultant used.

Is there a way to uninstall the product without this file (with some Registry edits for example). Thanks for your assistance.
