If you're getting an error that looks something like this please follow the steps below to solve it.
Uninstall your launcher
Restart your PC (this is important!) and then start the game, this will reinstall the latest version of the launcher.
If this doesn't solve it please download the latest VC++ bundle from the link below:

We recommend you download the x64 version first but if that doesn't solve it, give the x86 version a go.
