rekordbox 2.2.4 mac installer file

Been using 2.2.4 for as long as ive been using rekordbox. Tried all the updated versions but I find the newer versions complicate pretty much every task your trying to do hence sticking with 2.2.4. 

Bought a mac where I really want 2.2.4 on it but I cant find a file anywhere on the web. Already have an installation key so just need the installer file.
