SharePoint 2013 Installation

Issue 1:

During Installing SharePoint 2013 Prerequisites there was an error in installing Application Server Role , Web Server (IIS) Role : Configuration error

Steps to fix (Installing .Net Framework 3.5):

1. Insert the Windows Server 2012 installation image or DVD
2. Open a command prompt window (run as Administrator) and run the following:
3. Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\SxS /LimitAccess

Note: D:\ is a Label for CD Drive in my case where Windows Server 2012 ISO image.

Make a copy of ServerManager.exe and rename to ServerManagerCMD.exe - leave the copy in System32 folder.

or

rename the file C:\windows\System32\ServerManager.exe with ServerManagerCMD.exe and low and behold - it now works 

( I just copied ServerManager.exe to ServerManagerCMD.exe )
