In my attempt of installing and configuring SharePoint 2010 Farm, I have given a new Windows Server 2008 R2 box that should have SQL Server 2008.
So when I attempt to install SQL Server 2008 on it, I came across the following error message.
![sqlerror_thumb[3]](http://www.theangrycoder.net/image.axd?picture=sqlerror_thumb%5B3%5D_thumb.png "sqlerror_thumb[3]")
Not so weird because every server product have a set of requirement to be installed. First off, before you do any thing Just run the Windows Update. That’s recommended because there can be some thing else that is not mention in this post or any other but can hanged you for some time.
Ok now come to the second part of Enabling .Net Framework Core Role. For that you have to
1) Open Server Manager and Go to the Features on the tree available on left hand.
2) From the Features Summary, Click Add roles.
3) Following window will appear.
![selfeatures_thumb[2]](http://www.theangrycoder.net/image.axd?picture=selfeatures_thumb%5B2%5D_thumb.png "selfeatures_thumb[2]")
4) You have to check the top most option which is (in my case) .net Framework 3.5.1 Feature. That’s it
if you are installing SQL Server 2008 for SharePoint, make sure to check WCF Activation also, Like I did.
