Cannot open the project files or build the solution, even with a new project

For some reason Unreal can’t seem to build my project dll 's at all. It doesn’t matter if it is a new project or an old one, I cannot even open the editor.

I am using Visual Studio 2017, and the project does not build in there either.

Here are the errors I got from Unreal 4.18 when trying to create a new project:

The project could not be compiled. Would you like to open it in Visual Studio?

Sorry about the ugly error paste, but I am not about to put 4 indents on each one of those lines haha

Any ideas?


There seem to be a couple of things going on. Before delving into this further, can you launch the visual studio installer and confirm that you selected and have installed “Desktop Development with C++”?

Hey r0ss, I can confirm that VS has that installed, as well as “Game Development with C++”
