So, I recently got UE4 again, and for coding with C++, VS 2017 is required. I do have Visual Studio 2017 installed on my PC. However, in the wiki it’s mentioned that I have to install an Unreal Engine Installer package when I’m about to install VS 2017. So, in that case, do I have to delete the launcher AND UE4 and get the package via VS 2017?! Please do mention any way around this, as I really don’t want to go through the installation again. Thanks to all users who respond in advance! 
Just start the VS 2017 installer again, then click the modify button. You’ll be able to install more packages easily.
So I’ll have uninstall VS 2017 once again?
Okay, so I hit the modify button. However, there is no UE4 Installer package there under Desktop development with C++ still.
i think its in “game development” category
