Hi Andrew,
The Advantage Database Server is I think one of the core layers of the DB back end is it not?
I seem to recall a little bit ago that one of the fixes was to edit the file ADS... and enter some flag which I also found in the Advantage Database Server help.
So, my guess is that your dev guys are using a local copy of the server and I was thinking that maybe their is a collision with the local server and the 64 bit version of the database engine...
Geek geek geek...
Cheers, JK
