Reg Connector Software

We are using Sentinal DX 4000 NAS Box, and were trying to install a connector software into Windows XP SP3 system and its throwing an error which is mentioned below

The installation is cancelled

The Windows Storage Server 2008 R2 connector has encountered an unexpected error.  Click close to undo most of the changes that are made to this computer.

Might be a Media Center issue.  Look at this workaround and let me know.
