Here are some common issues starting up CommandBox and troubleshooting help.

Could not load library. Reasons: [no jansi in java.library.path ... Access is denied]

If you have a Windows machine which has been locked down to not allow DLL files in the user's appData folder, you may receive a message similar to this when attempting to start CommandBox.

Could not load library. Reasons: [no jansi in java.library.path, C:\Users\some.user\AppData\Local\Temp\1\jansi-64-9170657940034638384.dll: Access is denied]

If you don't have the option of changing the security controls on your PC, then you can try changing your Windows environment variables of TMP and TEMP to repoint to another folder which does not have this restriction.

/usr/bin/box: 87: exec: java: not found

If you receive a message like the one above, which was taken from a Linux machine, when starting CommandBox, this means that you do not have Java installed. You can solve this in three ways: 1. Download the JRE-included CommandBox install which comes with a folder called jre 2. Download your own jre and place it in a folder called jre in the same folder as the box binary. 3. install Java onto your machine and ensure the correct JAVA_HOME and JRE_HOME environment variables are set.
