If the Hummingbird NFS Maestro Client program is installed, when you attempt to install Windows 2000 Service Pack 4, you receive:

An error in updating your system has occurred.

If you press Cancel, your system is NOT fully updated and will NOT work properly.

To workaround this behavior:

1. Uninstall the Hummingbird NFS Maestro Client program.

2. Install Windows 2000 SP4.

3. Restart your computer.

4. Install the Hummingbird NFS Maestro Client program.

NOTE: The same problem can occur if you install 313664 on a SP3 system.
