Ok looking at http response a bit more information:

{"Message":"An error has occurred.","ExceptionMessage":"Method not found: 'System.Object Newtonsoft.Json.Linq.JToken.ToObject(System.Type)'.","ExceptionType":"System.MissingMethodException","StackTrace":" at Umbraco.Web.Install.Controllers.InstallApiController.StepRequiresExecution(InstallSetupStep step, JToken instruction)\r\n at Umbraco.Web.Install.Controllers.InstallApiController.PostPerformInstall(InstallInstructions installModel)\r\n at lambda_method(Closure , Object , Object[] )\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>cDisplayClass13.c(Object instance, Object[] methodParameters)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

If you look in Fiddler do you see something like this?

)]}',

Do you happen to have json.net in your GAC and if so, which version is it please?
I'm trying to fix this so would appreciate it if you didn't remove it from GAC so I have a test subject of updated version of 7.1 :-)

I have following in my gac

Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL
