I have installed:
1)Toad 11.6 x64
2)Client Oracle 11.1.0 x64 (with tnsnames.ora created)
I see all connection history and in the tab “connection using” i see the client x64 .
I can connect to all connections of the history but in the dropdown list of connection I can’t select nothing.
Three options : SQLNET EDITOR,TNSNAMES EDITOR and LDAP EDITOR are checked with “X”.
I’ve also copied user_files directory from Toad 11 x32.
Toad 11 x32 works fine with x32 client.
