Problem Toad 11.6 x64 on win 7 x64 and client 11.1.0 x64

Hi

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.
