While launching, Dreamweaver (13.2 and earlier versions) prompts you to install Java SE 6 Runtime.
I receive the message: “To open “PDF Studio 9” you need to install the legacy Java SE 6 runtime.” How can I fix this? A: Like other applications such as Dreamweaver or Creative Suite, PDF Studio requires Java 6 in order to run. Another reason for the reemerging prompt to download legacy Java SE 6 runtime is that a system might already have one out of three Java 9 updates or even Java SE 10, which are incompatible with the old version of the famous Adobe product. To run Photoshop CS3 on a Mac under macOS High Sierra, the legacy version of Java has to be installed.
Java SE 6/SE 7 Runtime is installed on the computer.

In Dreamweaver 2014, the prompt does not appear when you launch Dreamweaver. However, you are prompted to install Java SE 6 runtime while logging in to PhoneGap Build service (Site > PhoneGap Build Service > PhoneGap Build Service).
In the pop-up window that appears, click Install and follow the onscreen instructions to install Java SE 6 Runtime.
Note:
In Dreamweaver 2014, you can't log in to PhoneGap Build service without installing Java SE 6 Runtime.
Important: Ensure that you install Java SE 6 Runtime only by clicking Install in the pop-up window. If you install Java SE 6 or 7 Runtime through any other means (for example, by directly accessing Java.com), Dreamweaver could still display the prompt.
Even if you have installed Java SE 7 Runtime, you still need to install Java SE 6 Runtime as described above.
If you continue to see the prompt even after installing Java SE 6 Runtime as described above, perform the following steps:

Dreamweaver displays such a prompt because, when you update to Mac OS 10.9, Java SE 6 Runtime on your computer gets uninstalled.
