Install Java

Install the latest version of Java 8.
We recommend Adopt Open JDK, which you can download from https://adoptopenjdk.net/. Select the options:
- OpenJDK 8
- HotSpot.
If necessary, update the security settings to allow strong encryption and decryption of files.
For Java 1.8.0_151 and later, set the crypto.policy to unlimited for the JRE used by PhixFlow. To do this, go to the JRE directory /lib/security/java.security file.
The crypto.policy line is commented out.
```
# crypto.policy=unlimited
```
Delete the #" to uncomment the line:
```
crypto.policy=unlimited
```

We strongly recommend that you use the latest version of Java.

For versions before Java 1.8.0_151, you must install the JCE Unlimited Strength Jurisdiction Policy files.
