Dear Helen,

oooooppppppsssss, i have expressed myself wrong way, i'm sorry.

I do NOT interchange these dbs! Absolutely NOT!

I have to run several apps (each app access only ONE! database)
accessing InterBase or FireBird (separately) on one machine.

You mean to check and if needed to overwite, client library in system
every application start-up, please?

This mean i have IB7 client installed on the machine (v.7 client
library in the system) and fb client in app path, and it won't run!
(even if i put fb client in the system too, (replacing IB7 client))
I'm accessing FB server, of course.

Thank you for any response.
