Problem installing Remote Agent for Windows Server on Backup Exec 2010

Hi

    I have a problem with Backup Exec 2010 attempting install Remote Agent on a Windows Server 2008 Enterprise with Microsoft Exchange.

    The issue appears when I try to install through Backup Server the agent on the other server, and say: "Error connecting to the remote registry of server. Ensure that the current logged in account is not blocked from accessing the remote registry and that the remote registry is available before try again."

    So the account is not blocked, password is OK and got administrator privileges, but the error keep appearing and is not allowing install Remote Agent. How I solve this issue?

Thanks in advance.
Lucas.
