Demo failed in Visual Studio 2017

The demo opened OK and built OK, however, when I ran it in Internet Explorer I got Server Error in '/' Application
Exception Details: System.IO.FileLoadException: Could not load file or assembly 'System.Web.Mvc' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I am not sure that the problem is. I am running on Windows Server 2012 R2. Microsoft .Net Framework 4.5.1 and 4.6, 4.6.1 and 4.6.2.

I tried installing 4.0.0 but it said that a later version of this was already built into the operating system and installed. I did a search for ASP.NET but that does not seem to exist. I assume that it is part of the Framework?

Is DayPilot too old to work now?

I need to build a Timesheet application in a month and it looks like the ideal tool.

What are you trying to run?

1. The ASP.NET MVC 5 Gantt sample project

2. Or the Demo project bundled with the trial download:
