@Kilanny your answer is correct. Most machines in 2015 are 64bit, so there's a lot of chances that you just need to enable the 64bit option under the Tools main navigation link menu. No need to configure other files or hard code ports. Besides, port assignment should be dynamic. This fix applies to 2013 With Update 3 and Visual Studio 2015 Community Edition.
