How to install SQL Server Management Console in 2008 Express Version? I started a dozen attempts to install the SQL Server Management Studio for the 2008 Express Version of SQL Server. 

What i use:
Windows Vista 2007 SP 2

What i did:
a) I downloaded the install file SQLManagementStudio_x86_DEU.exe from Microsoft's Download Center

b) I started the setup and chose "Installation"/"Adding Feature"

c) The feature selection appears, but I can chose only from SQL Client Connectivity SDK

d) This is wrong I guess; but even if I click next I get an error message like "Please chose a feature first"

What can I do?

Thanks for any advice!!!
Do any of these links help?
