Don't install MSDE, instead install SQL 2005 Express Edition SP2. It is recommended by RIM: http://na.blackberry.com/eng/support/software/prof
Then install SQL 2005 Managment Studio Express
Go slowly through the SQL Express install choosing advanced / custom whenever you can and you can decide if you want to install as teh default instance or a named instance.
