Error to configure GRE Linux proxy

Hi,

I'm receiving the error:

ERROR: vmwaregre-agent was unable to load mount component

Check that you installed all required packages and
that your configuration matches all prerequisites.

when I tried to set the Linux Host. I selected the host and then set the path /var/proxy

In my host, I installed the VMware granular recovery extension agent and Virtual Environment Integration.

My DP version is 09.00 Internal build 87 and my vcenter is 5.5.0

Any idea ? Thanks
