Toad 4.6 and Windows 7 64bits

When I try to connect, I have this error:
SQL1159 Initialization error with DB2 .NET Data Provider, reason code 3, tokens C:\Program Files (x86)\Quest Software\Toad for DB2 Freeware 4.6\SQLLIB\bin\db2app.dll,

If you purchased Toad DB2, you should also be able to download the commercial Toad DB2 v4.7 product from the quest supportlink site at:
