Test connection failed because of an error in initializing provider. Oracle client and networking components were not found.

Hi, I have created a SSIS package using Oracle source. But i dont have Oracle components installed on my machine so getting error :

Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation.

Provider is unable to function until these components are installed.

I am searching online but dont know which components i need to install.

Can somebody provide me the link where i can download those components?

I am using 64 bit operating system and sql server 2008.

Thanks
