Error msg when installing

When I try to run MSDE setup, i get a msg (after a msg about starting to
configure) roughly like this: "...instance name is invalid" - how come?
Very grateful for help!
Hi,
Try running the setup from command line to install the MSDE.
1. Run command prompt.
2. Change the directory to the MSDE install extract folder
3. Run the following command:
setup.exe INSTANCENAME="testmsde" DISABLEROLLBACK=1 SAPWD="password" /L*v
c:\temp\setup.log
Thanks
Hari
