As #Nathan Dobie mentionned, instructions on the ROracle installation were helpful for me. I didn't need Rtools.exe but i had to add oracle instant client in the Environment variables.
Configuration in 64bits:
Under System variables, create OCI_LIB64 if it does not already exist.
Set the value of OCI_LIB64 to D:\app\admin\product\11.2.0\client_1\BIN (in your case)
Under System variables, edit PATH to include
D:\app\admin\product\11.2.0\client_1\BIN
And you will also need to create OCI_INC with the following value
D:\app\admin\product\11.2.0\client_1\oci\include
Worked very well for me :-)
