Delta2D Installation Instructions
The installation files dedicated to a certain operating system are tailored to a seamless integration into your operating system's look and feel.
The installation files for Windows and Linux include the needed java version as a private installation, only used by Delta2D. Any other java installation, installed prior to or after Delta2D, is not being bothered by Delta2D's java installation. And, vice versa, any updating of a system wide java installation will not interfere with Delta2D's functionality.
Depending on the version of Delta2D you installed, registration might be required.
