I am trying to install Umbraco 7.3 into an empty project using Visual Studio Professional 2013, and that Umbraco version is dependent upon .NET 4.5, which I should have according to Help > About
under Visual Studio, as the listed version is 4.5.50938. However, the package errored when I tried to install it with NuGet Package Manager, saying I didn't have the required version.
In trying to ascertain installed versions and checking my registry (as suggested here https://stackoverflow.com/a/199783/1140630), all the listed versions are v4 and below consistent with the error.
Any idea what I'm missing and why the mismatch? And why Umbraco shouldn't install: is it something to do with the Visual Studio .NET version not being in my registry?
