Hi Jens,
http://delphitutorials.de/VerbindungsdialogGehtZu
open Machine.config in
C:\Windows\Microsoft.NET\Framework\v4.0.30319\config (or your config)
and search for
<system.data>
<DbProviderFactories>
there are more than one Entry for the Firebird Client:
<add name="FirebirdClient Data Provider"
invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework
Data Provider for Firebird"
type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory,
FirebirdSql.Data.FirebirdClient, Version=4.5.0.0, Culture=neutral,
PublicKeyToken=3750abcc3150b00c"/></DbProviderFactories>
delete one of the Entry....
Regards
Wolfgang
