unable to do c++

ok for last few days I been trying to start a new project using c++ but no matter what I do theres all ways something wrong with visual studio ran in to problems with 2015 not having the right sdk and with 2017 ran in to not having a compiler for c++ when its there starting to feel like visual studio wants me to down load every ver of vs witch comes to 120 gb

You need to tick the following 3 options:

.NET desktop development
Desktop development with C++
Game development with C++

That should be enough to compile and run the editor. You do not need to install everything.

Actually if he is using vs 2017 and UE4.20 with Game development with C++ is enough.

Cheers!

nope I done fixed just need to reset comp and install vs 2017 and add unreal game engine from visual studio but thx for trying to help

The other 2 packages are only necessary to build the engine.
