[UE4 error]The project could not be compiled. Would you like to open it in Visual Studio?

Question

I saw many many people ask this question and apparently there is no absolute answer to this question.

this happened for me when I uninstall my visual studio 2015 cause unreal 4.18 no matter I do use VS 2015 and I want to use 2017 and I saw some people solve this problem with uninstalling VS 2015.

when I uninstall VS 2015 receive this error when I want to create a new C++ project:

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

I fix it with downloading this cleaner form this link https://github.com/Microsoft/VisualStudioUninstaller/releases . after that UE4 when you want to create new project sends a message and it says you don't have VS2017 don't panic just download the installer and modify it after that it downloading about 350 mg and after that, everything will get fixed. for more info : https://answers.unrealengine.com/questions/597939/new-c-project-fails-to-compile-using-ue-415-and-vs.html
