I am setting up some virtual machines and some of them are Windows Server 2008 R2 core with SQL Server 2012 SP1 core.
I was not able to finish the installation, because the error “ Object reference not set to an instance of an object” was happening :
The following error occurred:
Object reference not set to an instance of an object.
Error result: -2147467261
Result facility Code: 0
Result error Code: 16387
Please review the summary.txt log for further details
If you are facing the same problem, I solved installing .NET 4.0
Go to the :
\redist\DotNetFrameworks folder and install dotNetFx40_Full_x86_x64_SC.exe.
and be happy
