The Simplify Suite must be installed at the console of the terminal
server (i.e. session 0), not through a remote session.  There
are a number of ways to access the console:

- If it is Windows Server
2003, use the remote console switch.  If
you are unfamiliar with this option, please   
refer to the following Knowledge Base (KB) article from Microsoft (278845).

- Use a third-party utility
such as VNC or Dameware

- Use a remote KVM switch
