The single user license allows install on 4 computers at the same time, but only one copy can be used at a time. If I go beyond 4, I need to contact them at support@heliconsoft.com So they indicate no way to "uninstall" the license on my Windows machine. If I ever hop through more than 4 machines I will need to contact them.
So I can just install this on the Mac. It should run very fast. The Mac will be computer 2 of the 4. I doubt if I will ever get to 5 computers.
I double click the dmg and get a cute installer that tells me to drag both Focus and a 3D viewer to the application folder "thing" in the cute installer. They seem to install almost instantly. I do the same game with Helicon Remote.
They install with a 31 day trial. I find my 8 character activation code. I use Help->Register online and I am lifetime registered.
The remote I downloaded says it is x86, needs Rosetta, which won't be supporte in the next MacOS release. Did I download the wrong thing? Apparently not. I just delete it (move it to trash).
