Thank You Sean for your reply. As i expexted the AT app "is out of order" - meanwhile i tried to change the files.

Your suggestion
"Rather than try to have the existing app use v2.1, why don't you have
your application use v1.5? Replace the v1.5 embedded with a full v1.5
install and off you go."
worried me some, i wouldn't like to make step back and to use 1.5 instead of 2.1.
But if there is no other solution...
But i have (maybe naive) one question: can i share the database with one app using fbembed and one app using firebird client (the same version in that case)?

Robert

Although v2.1 will access a v1.5 database without issue.

There are several changes between the versions in how some SQL statements are handled that makes "blindly" change the engine/dll without expecting some code changes in the v1.5 application very difficult (if you were successful, it would be a fluke).

Rather than try to have the existing app use v2.1, why don't you have your application use v1.5? Replace the v1.5 embedded with a full v1.5 install and off you go.
