I get the error

Using Frontpage 5.x!

Starting install, port: 80.

Created: 24 Feb 2005 19:40:48 -0000
Version: 6.0.2.5516
Error: The server administration programs and the server extensions on the web server are not compatible. The administration program is too old to use with this server.


How do I fix this becuase I can't install FrontPage extensions.
Thanks in advance.
