During SQL 2012 SP1 installation on a Windows 2012 Server i got the following Error.
The installation finished with some error.
To fix this, first I need to install .Net Framwork 3.5 and then mount my windows 2012 media as D:\ and run the follwoing command as administrator.
Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs
I rerun the SQL setup and successfully installed it.
