I have 1 license and 1 copy of designer/admin installed. Can I have 1 copy of admin + 1 copy of non-admin installed under my single license. I want to have one set to 2020.3 and the other to 2021.x. I was given the impression by support that I should be able to do this, but it doe not work. 1) Is this possible (without having to purchase a second license), 2) do they have to be on the same physical machine or can I have one on my VM (Mac) and the other on my PC?
