- Go to WHM >> Cluster/Remote Access -> Setup Remote Access Key. It will automatically create remote access key on your server. Just access to it, don't need to generate the new key.
- Make sure file /root/.accesshash exists and permission is 600.
[root@server ~]# ls -al /root/.accesshash
-rw------- 1 root root 957 Mar 5 2007 /root/.accesshash
Try to install RVsitebuilder again.
