I am attempting to install SQL Server Management Studio to administer two instances of SQL Server 2008 Express Edition. One instance is 2008 Express and the other is 2008 Express R2. While attempting to install the management studio, I am told that I need SP1 installed for what I am assuming is the 2008 Express version, not the R2 version. It would be nice if I could acquire just the Service Pack 1 install file, not the entire package. After hours of searching, I cannot locate the file. I have the one for SQL Server 2008 (non Express), which doesn't work. It is either this or attempt to install SQL Server Express 2012, which I already tried to install and it is calling for Visual Studio 2012 shell? There seem to be 3 types of this shell, integrated, isolated and redistributable package? I have no idea which one I need? Has anyone been through this fiasco and come out on top? I would really like to complete this task. I have been at it for two days now. If you need any more information, please let me know.
