Database Software

Im using the following but having an error
Windows 7 64bit
Toad for Oracle 10
Oracle Oracle 11g (11.1.0)
Autodesk Mapguide Infrastructure 2012 64bit (Mapserver and Studio)

I can browse the database tables via TOAD but when I create a Data Connection in Infrastructure Studio 2012 using Autodesk FDO Provider for Oracle I'm having an error
"An exception occurred in FDO component.
The runtime was not found (module 'OCI.dll'). Please verify your Oracle client component installation."

Tried to set the Environmental variables but to no avail. What seems to be the problem here?
Here are some details

ORCL =

(PORT = 1521)
)
(CONNECT_DATA =

(SERVICE_NAME = orcl)
)
)
