The full version of Network Monitor does not install for single-user use, (for example, for an administrator working at the console). During installation you receive this message:
This problem can be resolved by setting an application compatibility flag.

Typically, applications installed on Terminal Server are installed for multiuser use. This would require that the application be installed after you place the server in Install Mode (change user /install), or when you install the application through the Add/Remove Programs option in Control Panel. However, since you normally install Network Monitor for a single user, the administrator would install Network Monitor in Execute Mode (the default mode or choosing to install for a single user in Add/Remove Programs).
When the server is in Execute Mode, software requests for the location of the Windows directory are answered with the user's Windows directory (typically located under the user's profile), rather than with the systemroot directory. Since Network Monitor looks for the systemroot directory as part of its version-checking routine, when the server tells it that the administrator's Windows directory is the systemroot, Network Monitor assumes this can't be either Windows NT or Windows 95.

Be sure to reset the flag after you have completed installation. Use the following steps:
