Oracle Adapter dll

Hi everyone!

When you install the Oracle Adapter the installation installs the dll of Oracle?? Or you have to install dll before the installaion?

I have this doubs becouse I have installaed the Oracle Adapter and when I try to use it I obtain this error:

Connecting to the LOB system has failed.
Could not load file or assembly ‘Oracle.DataAccess, Version=2.111.7.0, Culture=neutral, PublicKeyToken=89b483f429c47342’ or one of its dependencies. The system cannot find the file specified..

In assembly folder there isn’t this dll, then I have installaed the Oracle client but I get the same error, when i install the oracle client the dll is Oracle.DataAcccess Version=10.2.0.100..then…. where can I obtain the correct version??

Thanks..!
