What is not working?
There are several versions available, Active/Standard/Pro/Transit, 5/6/7(plus), with exe versions 9.15.3.376913, 471542..., couple of Revo editions, couple of Saratimi mods... you can use any you want dedicate to device resolutions. All are working with proper licenses.

I personally changed the software on several Becker models, i had no problems.
