Hello, I have two computers. One of them is Imac (Mac os High Sierra 10.13.6 Mid 2010) and the other one is Macbook Air (El capitan 10..11.6) . When i try to download Premiere or After effects Trial Versions, it says they are not compatible. When i try to choose from Creative Cloud, it doesnt let me choose older versions of Premiere or After Effects. Is there any solution for that? Thank you.
