Hello Ted-
The LabVIEW Installer builder stores the location of teh MSI installer you used to install the package on your system by default. When you go to build adn installer, it tries to copy the MSI files from that same directory, in your case this is the CD. There are a few ways to get around this. The first is to copy all of the installers from the CD to your hard drive and install them on your system from your hard drive. The second is to change the Installer Source Location setting in the Additional Installers section of your build specification. You will see that it points to your CD drive, but you can change it to any location that contains the valid files.
