VS Installer refreshing .cab

Does anybody know how to refresh the .cab file generated by VS Installer 1.1?
I have a text file that I would like to replace in the .cab file. I was originally using the Package & Deployment Wizard where I could just run the batch file located inside the Support folder and it would automatically refresh the .cab file for me, but now that I'm using VS Installer, it doesn't appear that such a batch file exists to refresh it.

I need to refresh it AFTER the package is already made, since I'm customizing each package for 50 different people. I've made a separate VB program that does the refreshing for me, but of course, it only works with PDW, not VS Installer.

Any ideas?

What about Inno, does anybody know if that provides a way to refresh a .cab?


Thanks,
