Problem: The administrator is not able to set the Install mode on the
machine. It is a VMware machine which the user is remoting into.
Root cause: That message indicates the Install mode is not needed as the users
are logged into an Administrator terminal service console session.
Solution: When
this message appears, you can proceed with the installation and do not need to
change the user mode to install mode. From an Administrator console
session, you can install without any issues.
