>I'm trying to create an installation package using the the new version (3.54 SP 4) of the InstallShield Express FoxPro Limited Edition. I'm trying to build a single image file.
>
>In the test mode (and actual installation) I keep getting error 1606. By the error message dialog, the error means that ISX can't read from a network location. However, everything is set for installation on a local machine, and the project is setup locally.

>I've gone through the docs (yes, I did RTFM and Mike Stewart's white paper< g >) and can find any reference to this error.

>Anyone else encounter this error? If so, did anyone find a solution?
