Errors On Install Of SQL Svr 2005 Enterprise

Greetings,

I have attempted a full install of 2005 Ent on our W2k3 Enterprise
server. When attempting to install all services (SQL Svr database,
analysis, reporting, notification, integration, client
services/components) I get the message: "The features specified are
not valid for this edition of SQL Server". I got the same thing
when attempting to install with various subsets of services. Then I
tried just database services and client components and got the
message: " There was an unexpected failure during the setup
wizard. "



Perusing the core.log, I see:

Fatal Exception caught while installing package: "10"

Error Code: 0x80070002 (2)

Windows Error Text: The system cannot find the file specified.



Source File Name: sqlchainingsqlprereqpackagemutator.cpp

Compiler Timestamp: Tue Aug 9 01:14:20 2005

Function Name: sqls::SqlPreReqPackageMutator::modifyRequest

Source Line Number: 196



Has anyone encountered this? One of our guys downloaded the install
files from Microsoft. We don't use CDs anymore. I think there are
files missing.



Thanks for any assistance with this.
