unable to connect to Oracle - cannot load OCI, please verify that oci.dll or ociw32.dll exists in your path

I am attempting to do a reverse engineer of an oracle database.  When I use the direct connection option I get the following error:

cannot load OCI, please verify that oci.dll or ociw32.dll exists in your path

I can connect to the database using TOAD and I can TNSPING the database. 

My path statement begins with Path=C:\ProgramData\Oracle\Java\javapath;C:\app\xxxxxx\product\11.2.0\client_1\bin;

The oci.dll and ociw32.dll files are located in the C:\app\xxxxxx\product\11.2.0\client_1\bin folder so the path does point to the needed dll's.

any help would be appreciated.
