Window 7 client -- RemoteUpdateManger -- failed to send the request to server to get the response - 404

I'm having issues running RemoteUpdateManager within a Windows 7 client.

Have successfully installed Adobe CC 2015 using Creative Cloud Packager.

However -- when i run RemoteUpdateManager -- with "as Administrator" -- the DLM.log -- states the following...

On the Windows 7 client -- I have done the following...

Disabled the firewall.

The Adobe Update Server is hosted on a Mac Server running Yosemite.

My mac clients are not having the same issues and run without issue.

Any ideas or suggestions????
