You need to install MariaDB Connector from: https://mariadb.com/downloads/mariadb-tx/connector

Select C++ connector and the platform you need.

Copy the /lib and /include into PSUnreal\ThirdParty\MariaDB

Right click on PSUnreal.uproject and "Generate project files"

When installing VS2017 I got this error while compiling Wordnet.

The file is under C:\Program Files (x86)\Windows Kits\10\Include\10.0.15063.0\ucrt

This was happening after switching from release branch (which contained 4.11 preview) to 4.10 branch. I checked and the file C:\Users\Luke\Documents\Unreal Projects\MyProject2\Binaries\Win64\UE4Editor-MyProject2.dll was old. I deleted all files older than today, then used

* git reset --hard
* git checkout .

Recompiled.
