When I compare the editions I see:
Remote Connection Management -> Macro support and automated macro -> Free/Enterprise supported
But when I check:
Ease of Management -> Macro/Script tool support ->Enterprise supported
Free Edition 126.96.36.199
This is an error on our web site but we plan to remove this limitation soon in RDM Free.
Sorry for the late reply, happy new year! :-)
And good to hear that the free edition will have support for macros so that edition we can also create our own macros.
