VB6 Package and Deployment Wizard Problem

I have been using the VB6 Application and Deployment wizard (under Vista, Service Pack 6) for some years without a problem to install a particular VB6 application. However a couple of days ago when I tried to install the application (under XP) it failed part way through the deployment with the error

Cannot find the source file 'C:\Documents and Settings\Clinton\My Documents\WG 6\Rally Install
@Mobile Bay - Confederate.mdb' to install

I had placed the .cab file, setup application and Setup script into that folder to run them.

I tried removing the file named but it failed again at a different file. Several other attempts after removing the file named similarly failed.

The install log gave no clues as to the problem.

I tried installing using earlier versions of the install files that were known to have worked previously without problem, but they also failed with the same error.

What am I doing wrong?

Thank you
