Hi Steve,
The file INSTALL.TXT is written to during installation when shared program files are installed, such as dictionaries. It is stored in the program directory (ie \softrak\icwin for Adagio Inventory), which means there is a separate INSTALL.TXT for each Adagio application. This file indicates whether each dictionary file overwrote the existing file or not.
You may want to check the INSTALL.TXT file to determine if a particular dictionary file was over-written or not. As per usual Windows installations, files with a later date are not over-written. If a file was replaced, it will have been saved in the \backup directory, such as \softrak\icwin\backup for an Inventory installation, if you chose the backup option during the install.
An error 1212 indicates a missing or out of date dictionary file. It could also mean that one dictionary of the paired set is missing.
This thread is talking about 3 different installations (Invoices, OE and IC), so the problem may be similar, but it isn't 3 reports of the same situation.
