Instance name specified is invalid

I am trying to apply the sql2kdesksp3a to a new
installation of SQL desktop. When I try and apple the SP
I recieve the error The instance name is invalid. I have
tried searching for the instance in the registry that is
reffered to on KB 311762 but I can not find any
references to the MSI file used for install. I am using a
select CD from Microsoft to install SQL Desktop. I dont
understand why this should be so hard I have not loaded
any 3rd part apps just XP and the SQL desktop and
Analysis services
no

instance is invalid

Error message during install:
Instance is invalid.
Just installed SP3a sql2kdesksp3.exe
Hi,
I think there is a instance conflicts. THis occurs if an instance of SQL
Server is already
installed on the target machine. To overcome this issue, you have to specify
the Instance name while running the setup.
Setup.exe INSTANCENAME=<name> SAPWD=<sapassword > /l*v c:\log.txt
Create a verbose log usinfg /l*v so that you can determine if installation
was successful or not.
Thanks
