FlameRobin on-disk structure support

Question

I use Firebird 2.1 on Windows 7 Pro.

I try to connect database with Flamerobin 0.9.2. It has worked before, but now I get the following error message from every database I try to connect to.

IBPP::SQLException
Context: Database::Connect
Message: isc_attach_database_failed

SQL Message: -820
wrong or obsolete version
Engine Code:335544379
Engine Message:
unsupported on-disk structure for file 
E:\tietokannat\oma.fdb; found 32779.15, support @4?.@5?

I have tried re-installed FlameRobin. I checked ODS version by gstat and database is 11.1. I can connect to database by Delphi 10.2.

Most I don't understand "support @4?.@5?" Before if I had tried to connect not supported ODS version, FlameRobin has informed properly like "support 11.1" Has something to do with the InterBase

Answer 1

I found that Interbase service was running on the machine. Flamerobin use that service, delphi 10.2 use Firebird. After stopping Interbase service Flamerobin started to work.
