.NET Core is not running in Windows 2008 Server R2
<p>I installed the <a href="https://www.microsoft.com/net/core#windows" rel="nofollow noreferrer">DotNetCore.1.0.0.RC2-SDK.Preview1-x64.exe</a> in my Windows 2008 R2 x64 machine. When I try to run a <code>dotnet</code> command the following error occurs:</p>

<pre><code>C:\Users\Administrator&gt;dotnet --version
Failed to load the dll from [C:\Program Files\dotnet\hostfxr.dll], HRESULT: 0x80070057
</code></pre>

<p>I double-checked that my OS is x64 and I'm installing the x64 version of .NET Core. Also, my installation seems to be okay, the file <code>C:\Program Files\dotnet\hostfxr.dll</code> exists on my machine.</p>

Maybe am I missing some pre-requisites?</p>
