Incompatible Project Type for VS 17 and VS 15

When I clone the solution and try to open in my desktop, I get a message that WingtipSassDataModel project type is incompatible.

I have Visual Studio Professional - here is the detailed message. Unsupported
This version of Visual Studio is unable to open the following projects. The project types may not be installed or this version of Visual Studio may not support them.

Non-functional changes required
Visual Studio will automatically make non-functional changes to the following projects in order to enable them to open in Visual Studio 2015, Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1. Project behavior will not be impacted.

Visual Studio 2017 doesn't support UML designers, which is the issue here. Hopefully they update this to 2017 so this can open cleanly.

Any news about a proper Visual Studio 2017 solution?

This seems relevant: "UML Designers have been removed."
