For those who face an issue related to the Mac installer, please re-download 3.3.44 from the Kemper website and update manually:
The description on the Windows version currently says "Windows 8 or higher". If you install it (and it will install on Win it launches (instead of Rig Manager 3,3.44) an error window which says that RM requires Win 10 build (whatever) and "you should update your Windows install" - so beware if you are not on Win 10 yet.
You might want to edit that and save the bandwidth
