4.14 Cannot open project anymore.
I added a C++ class to my Blueprint project and then the nightmares began. I am using VS Studio Enterprise 2015 update 3 & Windows 7 64.
Now it won't even open the project because it says "Missing Project Modules" - "The following modules are missing or built with a different engine version: Would you like to rebuild them now?"
If you say No, it just shuts down, if you say Yes, it shows "Error - Project could not be compiled. Try rebuilding from source manually."
and then shuts down.
My C++ code had some problems and was stopping the editor from launching my project. I thought that if the custom C++ code has bugs, then UE4 will not show my C++ classes in the Editor, or not compile the c++ classes at all, but in Unreal's case, the editor will not launch the project at all if the C++ code is buggy. This is one of the very scary quirks of UE. I can suggest a temporary workaround and it worked for me. See if this works for you.
Here is the temporary workaround:
This works for me. However, please note that I did not have much code and it was easy for me create a new c++ class from the UE4 editor and proceed with the compilation. The main problem is figuring out the dependencies.
Let me know if this helps. d0d0

You probably need to install the Windows SDK via the Visual Studio Installer.
I believe you need the Windows 8.1 SDK with VS2015.
Windows.h should then be in a path similar to
C:\Program Files (x86)\Windows Kits\8.1\Include\um
Hope that at least gets you on the right path.
