Instance specified not valid

Hi,

I'm trying to install MSDE SP3 which I downloaded from MS at http://www.asp.net/msde/.
Following the instructions as best I can I unzipped the file into a Folder now called MSDE located on C: I then went to a command prompt and typed in the command given to start the install:

setup SAPWD=testsite SecurityMode=SQL

Hit enter and the installer started up and ran for a few secs and then came back with

The Instance named specified is invalid

There was no mention of including an instance name or the format for it.

Suggestions please?

Also, if I want to completly uninstall MSDE if I need to how would I do it?

Thanks,
BobWell, I had this message come up if I tried to run setup for the instance that was already on the system.

I used this setup to install msde on my machine.

setup instancename="netsdk" sapwd="your password for sa" securitymode=sql

Reason for using instance name netsdk was that it seems that SDK kit needs this instance to install pubs and nwind database.

After executing this i did not get any error messages but when I started service manager I could not see any servers listed. It took me solid two hours to come up with idea to look into error log and there it was.

There is a line that says servername, I typed it in and I was able to start service. Log should be under c:\program files\microsoft sql server\mssql${your instance name}\log.

I am very new to windows world since I worked on Unix platform for past six years, so for you gurus out there this migth be something that does not need to be explained. Anyway I hope this helps.sql
