@robert That may be the case indeed. I'll see what more I can install. And sorry about not posting the errors, at the time I posted this I forgot it had given me a popup with a message before, saying this:
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.
For more information on enabling these project types or otherwise migrating your assets, please see the details in the "Migration Report" displayed after clicking OK.
- New Project, "D:\Works\Gamedev\Haxe\Kha\TestProject\build\windows-build\New Project.vcxproj"
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.
