W2003 Enterprise cool, but Datacenter ¿?

[Carlos Asenjo]

Hi, i have installed Plesk on a VMWare virtual machine with W2003 Enterprise x64 and on Select Componets window it shows:

AWStats
Webalizer

Database Management
SQL 2005
SQL 2008
MySQL Connector
MySQL DB Server
ASP.NET
PHPmyadmin
myLittleAdmin

Mail Management

MailEnable Mail Server
WebMail Client
SpamAssasin

DNS Servers

Antivirus

I installed it and everything ok


But some time after I tryed to install Plesk 9 on W2003 Datacenter x64 (with the same web installer) and some components dissapear!

SiteBuilder for Windows and Backup System was missing

I tryed to execute the same installer on Windows 2003 Enterprise and they appear again

Why happen this?? Anyone ever happened?

Thank you
