If you want to install Sql Server on a clean Win 2008 R2, you might get the following error:
Microsoft .NET Framework 3.5 SP1 Setup
---------------------------
You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5 SP1.
The thing is, you have to install the .Net Framework over the “Role Management Tool” – (so, in the end it’s just what the error message says). Try this:
Press Start –> Control Panel –> Turn Windows Features On or Off
The Server Manager is opened. Now expand the “Features” Tree, press ”Add features” on the right and select “.NET Framewok…:” and follow the instructions.
Easy, hm?
