Software Deployment

All, I have a project with a large number of files (37000) I have created the msi with the appropriate schema but have an issue (obviously why I'm posting...). There is an errant file in the package that I need to remove from the file table in the msi directly. I use adminstudio (installshield) and it cannot seem to display the file table (all I see is a -1 number of rows). I could use ORCA to remove this file, but I would like to keep this install as a setup.exe so that I can cache the entire msi (with cab streamed internally) using the webcache... property. Any suggestions? THANX in advance for any help!
