Installing MSDE

I've downloaded sql2ksp3. After I have extracted the file, I found MSDE folder and I ran the setup.exe. Halfway through the installation, it says the instance name specified is invalid.

Does anyone know how to fix this? Thanks.Take a look atKB article 810826 and specify an INSTANCENAME parameters to the command.

Installation seems to be OK but ...

Hello,
Yesterday, to start SQLServer, I have used the DOS Command
setup SAPWD=xxx from C:\sql2ksp3\MSDE.
I think tne mix mode of authentification is correct.
But when I want to connect to the database by SQLEntMan, it doesn't work ...
How can I connect to SQLServer ?
Server adress = name of the computer
Username = ?
Password = password of windows ? password of of SAPWD ?
Thank you any help
Benusername is sa
password is whatever you specified for sapwd
