Connector cannot start on client computer

Hello trouble shooters,
When I try to start the connector on the client computer it gives me an error message. The message states that cannot connect the computer, I am not running any software installation either in the client machine or with the local one. Then what might be the reason? I tried the common method of restarting both the machines, but no luck. Please help me to establish the connection, your help is appreciated.

Error:
Cannot connect the computer to the server because either another software installation is in progress, or, the computer has a restart pending. Either complete the installation process, or, restart the computer and try to connect again
