There are others but I think you are beginning to see a pattern here...
Also got the following:
Event ID: 1013
Product: Microsoft SQL Server 2005 Tools -- A component that you have
specified in the ADD_LOCAL property is already installed. To upgrade the
existing component, refer to the template.ini and set the UPGRADE property to
the name of the component.
Event ID: 11724
Product: Microsoft SQL Server 2005 Tools -- Install started.
Event ID: 11708
Product: Microsoft SQL Server 2005 Notification Services -- Installation
failed.
Hopefully this helps...
Thanks,
Scott

I can suggest you to download .Net 2.0 and install it seperately (just give
it a try and see if it installs it correctly.)
You can download it from the following address:
http://www.microsoft.com/downloads/details.aspx?FamilyID=0856EACB-4362-4B0D-8EDD
-AAB15C5E04F5&displaylang=en
Also, please be sure your Windows is up to date. And try SQL Server setup
again.

I re-installed .Net 2.0 and it still fails. Then I uninstalled ALL of the
.Net versions (1.1, 2.0 & 3.0) then re-installed .Net versions 1.1 and 2.0.
The install of SQL Server Developer Edition still fails. I am now getting the
following message from the System Configuration Check:
EDITION CHANGE CHECK
- Edition Change Check (Warning)
Messages
Edition Change Check
To change an existing instance of Microsoft SQL Server 2005 to a different
edition of SQL Server 2005, you must run SQL Server 2005 Setup from the
command prompt and include the SKUUPGRADE=1 parameter.
The install still fails with the same error messgage. But checking the
Application Event Log the large number of error messages that I listed below
are gone. The only error messsage that I got is:
Event ID: 107
Report Server Windows Service (MSSQLSERVER) cannot connect to the report
server database.
I am going to try and install once again.

Hello Scott!
Report Server fails if Report Server service attempts to connect to the
database that is not yet online. To fix it, you can try set a dependency to
Report Service.
Go to Regedit
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ReportServer]
Modify or create the DependOnService multi-word value to include
MSSQLSERVER.

I will email you a screen shot of the error message that I am getting.
Notification Services, Intergration Services and Workstation Components,
Books Online and Development Tools are failing with the message:
"A component that you have specified in the ADD_LOCAL property is already
installed. To upgrade the exisiting component, refer to the template.ini and
set the UPGRADE property to the name of the component."
