You can install a supported compiler. In that release, that was SDK 7.1, Visual Studio 2008 Professional, VS 2010 Professional, VS 2012 Professional, VS 2013 Professional, Intel XE 2011, or Intel XE 2013.

Note that none of the Visual Studio Community or Express editions were supported in R2015a: the only free compiler supported for 64 bits back then was SDK 7.1. That can be a bit of a problem if you are using Windows 8.1 or Windows 10.

I use R2015 and windows 8 what What can I do?

For windows 8.0 you might need to uninstall .NET in order to be able to install SDK 7.1, but you can install .NET again later.

For Windows 8.1, I am not certain if you can uninstall the interfering version of .NET.
