ISX strikes again !

My environment:

ISX_LE shipped with VFP 8
Win XP Professional SP1

At build time, I got the following warning:

Created release folders
** Warning: -3028: The string ID "ID_STRING2" was not found in the string table. It is referenced in the table:"" in column:"".

If running this installation an error

Error 1606.Could not access network location \.

occurs and installation stops.

Any idea how to fix this ?

I looked to www.installshield.com , but it seems that there is no support
available.

Part of a .log file which remains on a temp directory after unsuccessful installation:
