Unknown Database Connector Error using Crystal Report XI with Windows 7

My current configuration is:

Windows XP Professional

Crystal Reports XI Professional

Oracle Client 10g

This is working great, however we are switching to Windows 7 Professional and I need to get this same configuration working on the new machines.

I have loaded Windows 7 Professional and Oracle Client 10g. Oracle makes the data connection without any problems. I loaded Crystal Reports XI Professional, but it will not connect to the Oracle database. It keeps giving me the Unknown Database Connector error. Can anyone assist me with this problem? This is the final software package that is holding up the project.

Thanks
