Oracle client and networking components were not found.The components are supplied by Oracle.Provider is unable to function

Hi All,
     I have Oracle Client installed on  a pc and i have some asp.net apps that works with oracle using Oracle.DataAcess.Client
I can also connect to the oracle databse all fine.
but when i drag in the OLEDB destination and choose  the Native OLEB \Microsoft OLEDB Provider for Oracle.
I keep getting the error:

Oracle client and networking components were not found.The components  are  supplied by Oracle.Provider is unable to function

Any ideas.
It seems i'm missing a dll registry as SSIS  can't see it.
