Installing Sql 2005 on Vista - checkboxes grayed out.

When I try to install SQL 2005 Enterprise edition on Vista - the checkboxes for everything but what i think is the client tools are grayed out.

I get 3 warnings -

Sql server edition os system compatibility

iis feature requirement

edition change check

IIS is enabled, i have installed sp1(i thought this would fix the compatibility issue) and i think the edition change is because i have redone this about 6 times now - and it detects that i have done this before.

so i click next on the install wizard and get to the check box tree and the only one available to check is the workstation components.

what am i doing wrong?

Enterprise Edition isn't supported on Vista, which is why it's grayed out. You can install Developer Edition, though, which has all the features of Enterprise Edition.|||

thank you - this was very helpful. one more question.

is vista a workstation or a server? is the the xp pro replacement? is it the server 2003 replacement? or it is intended to be both? the documentation is a bit confusing.

this behavior suggests that vista is the xp replacement and is a workstation.

|||correct, it will be windows XP replacement. see http://www.microsoft.com/windowsvista/ for more information.|||

ok one more question - what is the server replacement? is it longhorn?

and thank you so much for clearing up the confusion :)

|||yes.
