If you get a message that the App is "damaged", then try either:
* Run Terminal, and enter: xattr -cr /path/to/TheApplication.app
* or, also in Terminal: sudo xattr -rd com.apple.quarantine /path/to/TheApplication.app
* and/or try rebooting or clearing your cache and re-downloading the DMG. Contact us if that still doesn't work.

Old-DOM Legacy Version ('Old Document Object Model')
If you are still specially required to use our 'old-DOM version for a particular project, use these download links.
Please note that as of June 2018 fewer than 2% of our active users are still on old-DOM, so we will no longer produce new old-DOM builds; however, we will leave a 'final binary release' online indefinitely, to assist with future conversion and so that users are left 'stuck'. Please contact us if you would like assistance converting your document to the new Document Object Model.
If you want help converting an old-DOM document to new-DOM format, please contact us for a free evaluation of the work: if the work is 'simple' we will do it for free; if it's complex we will provide a quotation.
