## The Launcher Handles Everything for You
|
||||
|
||||
The launcher validates the configured Java executable before each launch. If the configured value does not point to a valid Java version, your computer will be scanned for a valid version. If you do not have a valid installation, the game will not launch. WesterosCraft requires **Java 8 x64 greater than update 52**.
|
||||
|
||||
**Why is Java 10+ not supported?** Forge and LaunchWrapper [only support Java 8](https://github.com/Mojang/LegacyLauncher/pull/11).
|
||||
|
||||
#### Automatically Install a Valid Version of Java
|
||||
|
||||
The launcher will give you the option to automatically download a valid version of Java if it fails to find one. It will download it to `.westeroscraft/runtime/x64` as a local installation (only for the launcher). **We recommend using this option.**

#### Manually Installing a Valid Version of Java
|
||||
|

If you want to manually install Java rather than having the launcher do it for you, follow these steps.
|
||||
|
||||
* Download Java 8 x64
|
||||
* Windows/macOS
|
||||
* Download from [Oracle](http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html).
|
||||
* For Windows: Windows x64 (`jre-8uVERSION-windows-x64.exe`)
|
||||
* For macOS: Mac OS X x64 (`jre-8uVERSION-macosx-x64.dmg`)
|

* Linux:
|
||||
* OpenJDK (recommended): `$ sudo apt-get install openjdk-8-jre`
|
||||
* Oracle: [Instructions](https://java.com/en/download/help/linux_x64_install.xml)
|
||||
* Follow on-screen instructions.
|
||||
* Try to launch the game again, the launcher should find the version you just installed. If it does not, try setting the value manually.

#### Built-In Java Handling
