You have access to an account that is a member of the Local Administrators group, for example, egoadmin.
The required connection ports are not in use.
The default base connection port is 7869. EGO uses five consecutive ports from this base port (7869-7873).
You have turned off real-time anti-virus checking.
Doing this prevents performance degradation and other problems (in some cases, anti-virus software will lock files while scanning them, creating the potential for problems to arise). If periodic scans are required, a best practise is to schedule these during periods of cluster downtime.
If you customize the cluster name, cluster administrator, installation directory, or ports, you must use the same settings when adding a host to the cluster. Do not take the default settings when adding a host if you customized the installation on the master host.
Ensure the information you specify is free from typographical errors: the installation will not continue if there are errors within parameter entries.
