SIS Netview Install

[Matthew Clayton <matthew.clayton@ENTERPRISEWORKS.com>]

Well, now that I've tried to install Netview Server from SIS, it wont
let me install it the normal method. It keeps giving me the following
error: 

InstallOpsCatalog: 0017
The revision levels of the installation and media do not match "5.1 <->
(none)"

Incidentally, 5.1 was what I entered when it asked me for a version in
the SIS attempted install.

Any ideas?

Thanks!
