Dear Rickscr
I can't say I have heard of that message being returned during any phase of a DataCare check. File unit invalid messages usually indicates that the product in question (running during a certain function, or in this case being checked by DC) is using an unconventional process that is not recognized by the application being used, or one not recognized by the WSM version being used - or something to that effect.
To check the File Unit itself, while in the function being performed (DIC), press <ALT-F3> to see the file units in use, or <ALT-F2> to see the resources being used.
Here are more notes for you to further diagnose the actual problem...
1. DataCare V6.1A was released in 1994!
It is compatible with WSM 6.1 as well as other products that were released just prior to that time frame.
2. If your client is not using the 940616 release, but using 940204 - there could be other issues. The 940616 release fixed these problems, but I have no documentation this far back to further identify specific issues.
3. If your client is using such an old version of DC to check much newer ACCPAC Plus or ACCESS products, or is using a newer WSM than 6.1 - then all bets are off.
The currently shipping version of DC is V6.5A (001128). More information on it's compatibility with other products can be found at http://www.softrak.com/Comp_cht.pdf .
Hope this helps!
