Can't compile C++ code / Visual Studio Problem

Development Programming & Scripting C++
1

Hello,

I was following this video tutorial (Vid here)](- YouTube)

and at the part I’ve linked to when I was attempting to compile my first C++ class I got an error. It said I needed to recompile my project to see my script in the contents folder. I reopened the project and nothing appeared. Also Visual Studio didn’t open. The .h and .cpp files appeared in the source folder but that was it. At the time I had Visual Studio Community 2017 installed. After some searching I found I needed to modify my installation and add the modules for C++ for Game Developing and some others to get this working. So I modified these things but it fixed nothing. (Actually this step fixed an issue that stopped my project from starting altogether after I did the first C++ class attempt). I uninstalled VS2017 and installed an old VS2015 but this didn’t fix anything. I feel like there’s a simple fix to this problem.

Here’s the red/yellow error code lines in the log. There’s more since I uninstalled VS and reinstalled and it says ‘couldn’t connect to Visual Studio’ there now.

Install Visual Studio 2017 with all the options for C++ development enabled in options of installer panel

**Run Unreal Engine as administrator solved for me. **

Create a shortcut for Unreal Engine in your desktop.


 **Right click > Properties > Advanced > Check 'Run as administrator'**

Hi Jack,
I’m sharing you my vsconfig file which might help you to look for these components in VS for installing. This one I exported from Visual Studio 2017
