You can download a ZIP version of Astah that does not include a bundled Java Runtime Environment (JRE) from our official archive page. This is ideal for users who prefer to use a pre-installed JRE on their system.
Download Steps
-
Navigate to the Astah Archive Page.
-
Select your specific Edition (e.g., Professional, UML).
-
Select the Version number you wish to install.
-
Download the package labeled "Archive without JRE installer".
