Downloadolder versions

Hi together,

actually I´m using the C1 Version 21 Pro on my Mac and I want to load the version 12 Pro (My Fuji + Sony Cameras) because the 21-versions don´t run on my old Macbook Pro (Sierra).  In my opinion the 12 version worked with my Fujis and my Panasonic... Any suggestions anbody here - I would be glad!!!!

Thank you folks,

Sven
