insert CD dialog

The product I'm trying to install (using a Basic MSI package) spans
several CDs, and includes several components that a user could install as "run-from-source". When a user needs a component that was installed "run-from-source", I'd like to call MsiGetComponentPath() and rely on MSI to prompt for the proper CD and return the path to the key file. Nothing unconventional about that, and this works fine, as long as the component the user wants is on the first CD. But, if the component is on, say, the third CD, MsiGetComponentPath always returns INSTALLSTATE_SOURCEABSENT, without bringing up a dialog.

Below is some debug output for each case (when the component is on the first CD, and when it is not). The log files don't show anything of interest. There are some differences, but I'm not
sure what they mean, much less how to work around the problem. The main differences are two lines written when the component isn't on the first CD (but are not written when it is on the first CD):

Package validation of 'D:\RoadMate Data Extraction Tool.msi' failed

and

Cloaking enabled.

No idea what that means.
