Re: Harmony 2 and 3 on the same computer (Mac)?
I have H2.06 and Hv3 installed in separate folders on my Mac each containing the projects I am using on that version. When I changed to v3, I deactivated the Harmony Code Configurator in the plugins menu, then I selected (and/or installed) the Harmony 3 Configurator. Then I selected Tools/embedded/Harmony 3 Configurator. I checked all the paths that were displayed to verify they were correct. That worked.
To go to H2.06, I opened the H2.06 project, then deactivated the Harmony 3 Configurator and installed/activated Harmony Code Configurator. That brings up the old framework windows. Check the project properties and paths to be sure everything is as it should be.
This is not pretty, but it seems to work.
