Note: It is very important to have the latest service packs installed in your operating systems prior to installing Plesk Sitebuilder.

*** Since version 4.2, Microsoft Windows 2000 Advanced Server is no longer supported by Plesk Sitebuilder. So to upgrade from Plesk Sitebuilder 4.0/4.1, you will first need to migrate your 4.0/4.1 instance to a server running Microsoft Windows Server 2003 or Microsoft Windows 2008 Server OS. For a guideline on how to do this, see topic Upgrading from Version 4.0 or 4.1 to 4.5: OS Compatibility.
