Can I install Visual Studio 2013 on Windows Server 2003 R2?
According to Visual Studio 2013 System Requirements it is not supported. However I heard some users was able to install it. Was anybody able to install it on Server 2003 R2?
VS 2013 requires the .NET Framework 4.5.1, which in turn is not supported (and does not install) on 2003, you need Vista SP2 or newer or Server 2008 SP2 or newer. The same is true for VS 2012 which requires .NET Framework 4.5
