Symptom:

When running the software installer for a Wasp software product,  the installer stops and gives a prompt:

Title: Setup Needs The Next Disk

Text: Please insert disk 1 that contains the file [missing filename].

There is a Path field, and Browse, OK, and Cancel buttons.

If you cancel on this file, the entire installation cancels.

Cause:

The installer is expecting the specified file in the specified path, but it's not there. This could be because the installation files were incompletely copied to another location, the self-extraction process did not complete successfully, or some other reason.

Resolution:

Copy or extract the files again, then retry the installation.
